Greenday?!!! If Alexi and Billy Joe did duet vocals, that would be horrible!!! Greenday fuckin suck! If Alexi sang with him, it would be a big up for the sucky punk band but a downfall for Bodom. I can't stand Billie joe's voice at all. It's the worst vocals i'v ever heard. Just the way he sings, sickens me. It gives me a headache. And if they ever did punk, i think Alexi should do duet vocals with Derek Whibley of SUm 41. Now that would be something to look forward too.
