Best Surprise Guest You've Ever Seen in Concert

[Tassoula]

Bono's recent appearance with Glen Hansard made me think back to the times I've been lucky enough to see a surprise guest in concert. If I had to narrow it down, I think the two times that were most exciting for me were Brandon Flowers appearing in Vegas with U2 during Vertigo for "In a Little While" and Mike McCready jumping on stage with Cheap Trick in Tacoma, Wash. for "Surrender."

What are your favorite surprise experiences? U2 or otherwise...

[Mercurial]

I've never had any. Every time I see U2 in NJ, I hope that Bruce shows up, but only sometimes he's mentioned as being in the audience.

On the Elevation tour, they had Daniel Lanois do something with them, but that's not a huge stretch for U2 fans (nothing against Daniel).

Carlos Santana showing up at a Dave Matthews Band show in San Francisco 8 years ago.  I was never a huge fan of him, but it made for some nice guitar solos.

ive only had 2

Don Henley playing with teh Doobie Bros. in Texas in 2010

and

Gwen Stefani with U2 in Dallas Elevation 01 singing .......oh what was that song? with like 9 pop stars from 01?

anyways No Doubt opened that show so it wasnt that big a surprise.

When Kings of Leon opened for U2 Eddie Vedder came on stage and sang a song with them. When I saw Aerosmith Nikki Sixx of Motley Crue played Helter Skelter with them.

Not much of a surprise as my then fiancee and I were sitting next to he and Ali in the guest area.

She was on crutches due to a ski accident. A kind bouncer took pity "stuck" us in the guest area by the soundboard where we could sit (standing only venue). Couldn't quite believe wo we were sat next to. Exchanged a few fawning words, but left them alone.

Hope they had smelling salts nearby! What a memory!!

You were there? I just watched the DVD of that show again the other night. I Still Haven't Found What I'm Looking For with Springsteen was epic.
