The only song I'm really surprised they dropped is Keep Yourself Alive. It even suits Paul Rodgers' voice better than some of the songs they asked him to sing.
Yeah, there have been a few which have been reintroduced since Rodgers that I have thought would have suited him.
I'm not sure how they developed the setlists with PR, but a telling remark in an interview with him at the time was that he didn't like singing "very wordy songs" and "preferred songs with space in them".
I do know that during rehearsals he was having problems with Hammer to Fall, which may have led to the re arranged slow version. .
Queen set lists were more exciting in foreign countries for there fans especially the japanese fans who got extra treats from the band.
Uk got same old set lists and nothing special either! What disappointed me was songs never changed very much from one tour to another, the perennial anthems remained
and they never explored songs they had ignored like "Who needs you" or "Funny how love is"
The setlist and set were great. The lighting rig had a huge presence. Roger's use of electric pad/triggers wasn't good.
The Keyboard solo grow out of an idea to play Machines or back to Humans, which they didn't rehearse and never played, but decided to use as a keyboard solo and extended break for Roger and Freddie, leading into Brian's solo.
