Hmm I'm not sure it's such a good idea to be honest. Looks like they're jumping on the Green Day bandwagon here with getting people to perform live on stage. Other artists may have done this previously, but Green Day have done it for years and they don't rely on people uploading videos, they just randomly pick someone from the crowd. It's almost as if Jon's said, look this is summat we need to do. I can't sing the chorus anymore anyway and it'll tick a box for us live as well by letting some fans come on stage and do it.
