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.
Resistance is futile. You are now an orb.
