Can someone help me out with the following song lyrics:

1.  This song is really old it's a jazzy song and goes, "He's my baby, I don't mean maybe he's my baby now"
2.  This song is played on the ferrero rochelle ad (raffellos chocolates commercial) and has the words, "Bring on the night, bring on the night" (dance song very repetitious)
3.  This song is an old folky song a very melodic ballad and in the chorus it goes,"Ooooooooo-la, la,la - ooooo, la, la, la" something like that that's all the words I know sorry I think it's sung by a group a male vocalist.

Does anyone recognize the title of these songs and the singers please? 

"no" to all three.  Only hint I can give you is that the chocolates you're talking about are probably "Fererro Rocher"...

...and that they're darn good eatin'.

1. Could it be "Yes Sir, That's My Baby?" That one goes, "Yes sir, that's my baby. No sir, I don't mean maybe. Yes sir, that's my baby now." This is probably wrong as I've only heard this sung by male vocalists, but it might be a possibility worth checking out.

3. Long shot, probably wrong, but Faces had a song called "Ooh La La" that was somewhat folky. Some lyrics:

"I wish that I knew what I know now
When I was younger
I wish that I knew what I know now
When I was stronger"

Sorry, I doubt either of these is your tune, but all that occurred to me in both cases.

Thanks guys for your help. Does anyone happen to know the songs I mean for number 2 (Ferrero Rocher ad) and for number 3?
