it's been posted in every booklet since GREATEST HITS 2...
its in every bio and pretty common knowledge that the theme of It's A Hard Life was lifted directly from that opera.
probably why the video was such a gaudy embarrassing thing (for the rest of the band at least)
I can't really tell much with the song per se BUT I still love the Queen song and short promotional films. Phenomenal and pioneering still just the same. Not to take away from Mr. Pavorati either. He must not have been to concerned with it as he ended up doing great work with Brian May at the Pavorati And Friends Concert.
