Is it possible to get backstage passes or, whats the best way to meet Keane?

 I don't know about backstage passes, but the best way to potentially meet Keane is after the gigs.  Fans usually wait near the tour buses, and if they don't have to rush off right away after the gig, the guys are usually pretty good about coming out to sign autographs and chat for a bit. :)

Wish I could have an autograph in Manila.... I wasn't able to do so the last time they were in Singapore...

I had a chance to meet them after their gig in L.A. They are just the loveliest, most polite bunch! They each took their time signing autographs and posing for photos. They even hung around to chat with fans who had waited an hour before they showed up. It was an unforgettable experience - something that I would wish for every devoted Keane fan.
