Definatly, Cherie is the one with the blue pants - I could tell that even without the vocals. They don't look exactly the same... But they do have a unique sound. I just love it.
Interesting, I think this is the one song that has the instrumental solo before the bridge. Every other version I've heard replicates Russ Ballard's original arrangement, with a false ending leading into an instrumental solo followed by another run through of the chorus. And just for the record, Russ Ballard wrote and recorded this song in 1976, four years before Rainbow did it. It was also done by Head East and South African girl group Clout.
