it goes like the live version on live killers.
pretty much the same as the record but with a longer middle drum/vocal section before the guitar solo.
freddie on piano except for that bit where he got up to sing
I always thought it was a great song live. I have heard a good few versions from a few different concerts - tough one to play (piano) and sing live. ... I can never remember the words and play at the same time, so I stick to playing keys and leave the singing to the professionals.
