let's see, so far:
Al Green - Sha La La
Chicago - Old Days
Disco-Tex and the Sex-O-Lettes - Get Dancin' - Didn't the Muppets cover this?
EWF - Shining Star - someone should name an energy drink after this song: "Make your body big and strong"
La Belle - Lady Marmalade - someone should name a fruit spread after this song
(then some other song - NTM, sounds like Bonnie Raitt?) Suzi Quatro - Your Mama Won't Like Me
KISS! - RnR All Nite
10 CC - I'm Not In Love - I think this was a radio edit version... I heard a cut I wasn't expecting.
