Rod Stewart’s “Hot Legs” first appeared on the November, 1977 L.P. Foot Loose & Fancy Free and was released as a single in early 1978. The tune (co-written with Gary Grainger) hit #28 on the Billboard US 100 and #5 on the UK charts.
Here’s Rod “The Mod” performing the song on German TV in ’78. Just Stewart and his legs (and, I’m guessing, a pre-show tipple). Hot!
