I've seen singers that were once so popular they've been relegated to 100-capacity pubs. Quite sad - but if U2 do nightclub spots, I'm there - especially a cheap U2 show.
Twitter just got flooded with a link to an NME story about Glasvegas being dropped from their label, and the bottom had a little tag about that. Then I believe it was @U2 tweeted about the Coldplay rumor, though they said there was nothing in print.
