Bono joined Bruce Springsteen on stage tonight and there was a big reaction

A surprise guest.

Some people aren't having the best time at Bruce Springsteen due to issues with the sound but to be fair, The Boss puts on a serious show. Thanks to social media, you feel like you're (almost) at the gig and Bono just joined Bruce on stage for Because The Night. Unsurprisingly, Twitter went mad for it.

Those poor people at Bruce Springsteen. First their I-Tunes and now Bono forces himself into their concert. Haven't they suffered enough?
