People have discussed that in the past- even back in 09 when 360 was just starting, and everyone wondered whether or not Bono would wear that eyeliner on tour that he had in the press photos (and at the Grammys), we thought it was a "modern MacPhisto"...and I think he's better left in the 90s. He's too old to pull off a "character".
I agree with Matt, Bono is to old for that kind of role playing and he is a different person now than during the Zoo TV period, he was a lot cooler back then imo. He didnt gave a shit about everyone's opinions , or at least that's what it looks like to me.
He's still got quite a bit of swagger, just not the young spark anymore. He's aged well, performance-wise...I still think he gets a place going like few others...he just doesn't need to be bringing a character into it. They're also not playing songs that would really merit one. I think the Mirrorball Man was too much in 92, but MacPhisto was golden...though if he hadn't been singing Daddy's Gonna Pay and Lemon, he would have been out of place.
Bono was awesome during Zoo TV, not so much during Pop Mart, great during Elevation, shit during Vertigo and he is still a cool dude now. He is a great performer and a great singer too, there arent many artist who have both.
I thought the Vertigo days were okay minus the speeches. Definitely his talkiest tour.
Also I really didn't mind him during PopMart either. He never really did that much because they didn't really have a stage to run around like they have on every other tour post-92. The whole boxer look in the intro was kickass.
