Demitrius, you didn't help at all! Ha, still funny though.
Sara, you should've asked me! Wait, I wasn't online today. Anyway, what Freddie would do while Brian or Roger sang? I reckon that Freddie would go backstage and get a BJ from some bloke he'd just met, or have a few lines of coke. Or change his costume. I'm a bit serious in that answer actually. I read it somewhere in Guitar World.
He really had the stamina to do all that during breaks...Even between songs!
I'm so pissed I could spit.
