Does anyone know who sings this song, and if so where I can download it from?

I don't know the name or the artist, but the lyrics are something like this..

Back to rita and her big old butt, back to rita and the dance goes on, shaking it, shaking it all night long
She's dangerous on the dance floor

Sounds like "Dangerous On The Dancefloor" by Musto & Bones from 1990.  Hope This helps.

I know a girl by the name of Rita
light skinned Puerto Rican, I call Mita
the way she moves i can't ignore
shes a porno flick on the dance floor

twistin churnin drips of sweat
a little bass thump, rita's wet
once she's thru fellas flock to her
girls clock while the beat just rocks her side to side
the beat goes boom
the new jack is up sayin give me some room
once again rita's ready with a smile on her face
the crowd breaks north givin rita space
big butt movin' n strokin' pattern
the crowd made a cirle like the ring around saturn
as for the new jack he just consumed
his body mutilated like he just been chewed

she's dangerous on the dance floor
she's dangerous on the dance floor
she's dangerous on the dance floor
she's dangerous on the dance floor

puff puff goes down the house
the latin n satin make the big butt bounce
swing it left to right and right to left
the video venus dont miss a step
she wears leather n lace a skirt made of satin
you like her, ya love her, dont love the loose latin
on and on she'll never stop
its party time n she wants to rock
one by one her buttons drop
little wiggle in the middle
no more top
the bassline comes, rita jumps
she humps pumps n throws those chumps
fellas flock to her 3 or 4
2 of em leave cant take no more
always ready rita's ready triple x
on the dance floor shes havin sex
takin em on two at a time
her lips her hips n her big behind
what's this rich kids says 'excuse me miss'
rita's not havin it
'but i insist either bust a move or move your bust'
your breasts your chest or your big ol butt


back to rita and the dance floor porn
shakin it shakin it all night long
keep it up dance
how long can u last?
the tempo's fast
shake that ass
move it move it every position
flow go, no intermission
the crowd is drawn
fellas droolin
girls can you do what rita's doin?
ho style loose n wild
her style mean wow youll smile at yer f'in dial

she's dangerous on the dance floor
she's dangerous on the dance floor
she's dangerous on the dance floor
she's dangerous on the dance floor

guys stop to watch the x-rated dance
some are shamed by the stands in they pants
your heart stops, mouth drops, pulse is weak
pant like a dog from the body heat
she wore butt huggers
they were snug as a bug
my advice to the brothas
wear Jimmy & Cluggs
no one can chill cuz they all attracted
to her over the shoulder boulder holders
strapped in her back end
back to reality back to life
back to the beats of friday nights
hurt me hurt me worse know why?
people cant party its no surprise
dont slip dont trip just hold yer grip
she's rita go see her she's fully-equipped
goin round n round
up and down
stompin her feet
against the ground
guys eyes glued to her thighs
rise on they thighs, 9 inches high
the latin in satin some call her a stripper
shoulda zigged but ya zagged
and ya broke ya zipper
always ready ritas ready givin ya more
shes not at ya local video store

she's dangerous on the dance floor

bass's thump bouncin off the wall
rita wont drive cuz she's havin a ball
this urban queen rules the hip house scene
lean mean n full of steam
breakin all back standin on the block
in the middle of the dance floor youll get rocked
rita's rugged
leave her alone
she get you on the bone
send you home
porno flick her performin' art
on the mark rita's ready to start
move smooth in the groove
rita will prove she's in the mood
dirty dancer she does it best
6 feet under is where you'll rest
6 and 9 on the behind
just like fine wine she improves with time

from dawn to dusk she'll do it all night
i hope u can see her this friday night
but if you cant dont get uptight
someone's always on em with the mic at night
crank it crank it pump that bass
rita's wearin leather n lace
big butt swingin from left to right
drippin n strippin on a friday night
she rita go see her
light skinned mira
times runnin on your meter
so meet her, Rita
move me move me rita moans

if youre lucky she'll take ya home
to a penthouse apartment on Cribben Road

starring rita and her booty

I know a girl by the name of Rita light skin Puerto Rican; I call Mita
The way she moves I can't ignore she's a porno flick on the dance floor
Twisting churning drip of sweat
A little bass thumps, Rita's wet
When she's through fella's flock to her girl's clock while the beat just rocks her side to side
The beat goes boom!
The new jack is up saying give me some room
Once again Rita is ready and a smile on her face
The crowd breaks north giving Rita space
Big butt moving in a stroking pattern
The crowd made circle like the ring around saturn
As for the new jack she just consumed his body mutilated like he just been chewed.

She's dangerous on the dance floor....  Dangerous

Huff puff blows down the house
The Latin in satin makes the big butt bounce
On your left to right and back right to left
The video venus don't miss a step
She wears leather and lace; A skirt made of satin
You like her you love her
Don't love the loose latin
On and on she'll never stop
It's party time and she want to rock
One by one her buttons drop
Little wiggle in the middle
No more top
The bass line thumps
Rita jump, She humps, pumps and bumps those chumps
Fella's flock to 3' to 4'
Two of them leave; Can't take no more! 
Always Rita
Rita's ready triple XXX
On the dance floor she's having sex
Taking them on; Two at a time
Her lips her hips and her big behind
What's this french kiss? Excuse me miss
Rita's not having it but I insist.
Either bust a move or move you bust.
Your breasts your chest or your big o' butt
Back to Rita and the dance floor porn
Shaking it  shaking it all night long
Keep it up! Dance! How long can you last?
The tempo's fast
Shake that ASS!
Move it move it.
Every position
Flow go no intermission
The crowd is drawn
Fella's drooling
Girls can you do what Rita's doing?
Ho style
Loose and wild

Mean while you'll smile at you FM dial.

Some ashamed by the stance in their pants
Your heart stops mouth drops pulse is weak
Panting like a dog from the body heat
She wore butt huggers; They were snug as a bug
My advice to the brothers were jimmy at clubs
No one can chill cause they're all attracted to her over shoulder bolder holder strapped to her back end
Back to reality

Back to the feature of friday nights
Hurt me hurt me
Word to the wise people can party it's no surprise
Don't slip don't trip just hold your grip
She's Rita! Go see it! 
She's fully equipped
Going round and round up and down; Stomping her feet against the ground
