Daisley replaced Jimmy Bain as Rainbow's bassist in January 1977. He would only spend about a year and a half with Rainbow, but it was the springboard to his work with Randy Rhoads on Ozzy's first two albums. Bob never wrote anything for Rainbow. Dio tried to form a band with Daisley two times (in 1979 and again in 1983) after they left Rainbow in '78. Bob's time and tone here are killer. He really propels the band. Jimmy Bain co-wrote this song and played it on the first leg of the "Rising" tour. Bob mostly kept Jimmy's bassline, but there are a few differences. Bob and Cozy Powell were a powerful team. You can hear Jimmy's version on Rainbow's "On Stage" album.
