Springsteen Joined U2 On Stage At Madison Square Garden And It Was Epic [VIDEO]

So you're at a U2 show in Madison Square Garden when all of a sudden Bruce Springsteen appears onstage and joins in on two tunes, that'll make your night!

Springsteen joined in on 'I Still Haven't Found What I'm Looking For' and 'Stand By Me.' Unfortunately the sound quality is really never very good from these crowd videos, but this isn't too bad; here is another video, same show, different location in the venue.
