I Can Dance

Leo Sayer was a British performer that scored some top ten hits in the USA during the 70's, including two #1's... "You Make Me Feel Like Dancing" and "When I Need You", both in 1977.  The strength of those records is probably why we forget his  first hit in the USA, 1974's "Long Tall Glasses (I Can Dance)". Such a great song, and extremely popular with local bands it just dropped off the radar and slipped into the forgotten oldie category.
