Cheryl Lynn, this was the jam. Funny thing about the 70's (late) every time I go to a wedding, and the band takes a break, the DJ breaks out with all of the hits (dance/disco) hits of the 70's & very early 80's----best way to describe that era is music is universal. Oh by the way Cheryl is lip/sync they did not sing live on Soul Train, that was the new thing back then.
