Are you referring to the "Mama Mia"/Opera section? It's always been done on tape.

Yep, that section. I remember seeing them and was uber excited when they started playing. Then... 'bam', the stage goes dark, with some stage lighting doing basic crap. I could not believe it.

Maybe Freddie was a perfectionist. Pink does a fine job of it.

And maybe this event really solidified my hate for artists lip-syncing their own songs. Jesus, if you can't sing it, don't play it... and certainly don't play a tape of it.
