Speaking about the similarities and differences between Mercury and Lambert, May said: "[....] When Adam walks onto a stage, it's not Freddie, and it's not him trying to be Freddie, but when Adam walks on and when Freddie walks on, something happens; there's some kind of catalytic action that happens between people, and it's a very rare and special thing. So I would say that's something that Adam and Freddie share, and I know that Freddie would agree with that. I mean, without even speaking about the voice. I mean, the voice… they both had, and have, incredible voices — the kind of voice that you don't find in a billion people. And, of course, the voice is very special, but it's not enough. You have to have the will and the spirit to use that wonderful instrument that you've been given to make that connection."
