Green Day bassist Mike Dirnt has told NME that going back on the road after frontman Billie Joe Armstrong's stint in rehab is going to be "nerve-wracking," adding that the band and its crew will be watching out for Armstrong's well-being. Dirnt explained, "What I will say is backstage is going to be a lot different from now on. We'll watch for stuff getting passed around, not let idiots walk backstage, not get hammered and s*** like that. When you're in a band, everyone in the world wants to have a shot with you. But if you have a shot with everyone in the world, you'd be dead."

Armstrong entered rehab in late September after a meltdown at a Las Vegas festival, later admitting that he had been addicted to alcohol and pills for years. The band went on hiatus for six months during his recovery.

Dirnt said about Armstrong's situation, "It was the first time in my life I've ever been in a position of being scared for my friend's life . . . I was shocked. The first thing I did the next day was call Billie and go, 'What the f***, dude? You're in a bad place, you've got to get better.' And you know, he took it seriously."
