The home of Radio 1's Live Lounge.
Gaslight Anthem came into the Live Lounge and performed their new single The '59 Sound and a cover of Kelly Clarkson's I Do Not Hook Up.
They talked about their musical influence and pal, Bruce Springsteen - apparently "he's like your dad but cooler!".
They told Jo why performing at Glastonbury is so important to them - essentially it's "because it's legendary and a big deal in America". They planned on doing it properly too - camping out in the fields with all the punters to have the complete Glasto experience.
