Mmmmmm...........He did actually. I think it was how good his voice was at the time. They would change the tempo of the concert to give themselves a breather after opening heavy and fast. One change came when he would build himself up for a few seconds and do this track. It's from an opera called 'Pagliacci'. You may not have heard it in America? From about 84. Not a great crowd pleaser, but they did it for a few years.On another note<---see what I did there?....I find it a bit curious and somewhat disappointing in viewing Queen live performances Freddie rarely attempted replication of studio recordings with the falsetto. To be fair many vocalists altered melodies to facilitate live performance, avoiding the risky high passages. Hey, you could have just stayed home and put on the record if strict adherence was your expectation, eh? Still, it was a signature aspect of their sound.
Maybe that guy resolved that issue for the film?
One thing to remember about Queen is they knew their songs on record had to be commercial. Live was 'f*** that! .......... 'Give em what they want!' ......... We will rock you! .... So falsetto wasn't always the order of the day.
