Ray Foster: It goes on forever, six bloody minutes!
Freddie Mercury: I pity your wife if you think six minutes is forever.
John Reid: So, tell me. What makes Queen any different from all of the other wannabe rockstars I meet?
Freddie Mercury: I'll tell you what it is. We're four misfits who don't belong together, playing to the other misfits, the outcasts, right at the back of the room who are pretty sure they don't belong either. We belong to them.
Brian May: I didn't know it was fancy dress, Fred.
Freddie Mercury: I've got to make an impression, darling!
