I found this in a interwiew.... well... read the last lines ... well...Freddie is wrong now.
Freddie: We've all had ego problems, like any other group, but we've never actually let it go that far where we actually said OK let's forget it, because I think we've all, the four of us have actually said that this chemistry that's worked has really worked for us, so why kill the goose that laid the golden egg, and, er, the survival instinct that I have in me and I think the whole group has, through any thing we will just carry on, you know, until one of us drops dead or something, we'll just replace. I mean if I suddenly left, they have this sort of mechanism, you know, and they'd just replace me. Not easy to replace me, huh?!
The tour isn't about Paul Rodgers trying to be Freddie or replacing him. Brian, Roger and Paul are just three respected musicians who felt they had chemistry together and decided to tour. It's not like the three of them are touring together as Queen. It's Queen (Brian and Roger being Queen is an entirely argument, though!) with Paul Rodgers. He's not trying to be Freddie, he's just their lead vocalist.
