I just learned this. 2/5th of Moving Sidewalks = 2/3 of ZZ Top

99th Floor - Moving Sidewalks

Moving Sidewalks were an American rock band formed in 1966 from Houston, Texas. They released several singles and an album, before bassist Don Summers and keyboardist Tom Moore were drafted into the army, bringing the band to an end. Guitarist Billy Gibbons and drummer Dan Mitchell then formed the band ZZ Top.
