Larry has seemed miserable/uncomfortable/annoyed with any PR related event for YEARS. The Facebook Q&A was no exception and cemented the fact for me that if there is a Carpool Karaoke episode, there is no way he will take part. It also made me wonder if he'd really rather not embark on JT30 at all...
I'd bet it's just Bono and Edge, Larry and Adam like to pass off that PR stuff to them
This would be lame, but I could see this happening. I think Adam might willingly join in, but Larry has always struck me as the type to not be keen on this sort of thing. He skipped doing a voice over for U2's Simpsons episode, he's avoided other "fun" stunts in the past, and he looked kind of miserable at the recent Facebook Q&A with the band.
It's really hard to say. There's been "talk" about Larry's attitude in the past, that he's only stuck around for the money. I'm sorry, but I find that hard to believe. The guys have been doing well financially for a long time and I'd think if any of the members were truly miserable, they'd leave. No shame in that as just about every band undergoes lineup changes at some point (that's not to say any member of U2 is replaceable, just that fans are super lucky to have had the same lineup with no changes for 40 years...name another band that's lasted that long with zero lineup changes).
It seems like Larry still enjoys making music with his friends/bandmates and that's why he's stuck around. It seems like he's always given off a gruff/annoyed appearance to fans, but we don't know what the man is like personally. For all we know, he's shy or a super serious type that doesn't mean to come off abrasively. He's always struck me as a no nonsense type, which I honestly think balances the band out in a good way. So while I'd be disappointed to see him not participate in any stunts or things like Carpool Karaoke, if it's something that genuinely makes him uncomfortable? Who can blame him for not wanting to join in.
