Yes U2 is still that popular despite what trendy haters may like to believe. And he injured his arm. Even if by next summer he's not fully healed all he will have to do is wear a cast on his arm.
also @NotoriousTIMP the reason your code didn't work for the second night is because they limited the U2 presale tickets to two per person this time, instead of the usual four. Which totally sucks because now we all have to fight scalp bots for tickets on Monday morning or just pay twice as much from scalp bots on stubhub. I feel like U2 should give all of us Experience members a new code for all getting fucked over so hard in that first round of presales.
