i wouldn't ask this but i will do my best. green day is a band, so it's pretty much go green day. i know, it is not a very good explenation, but i did my best Green day has been a band for about 18 years
Green Day was a little more popular, but after nickleback made the album called "Dark Horse" they became less popular and Green Day made 21st Centery Breakdown Green Day became more popular and the are making a Green Day Rock Band :)
Ha, this question make me laugh. Green Day is certainly not dead, and they have been touring recently aswell, also as their alternate band, The Foxboro Hot Tubs. Green Day are also active with a new Rock Band game and of course their huge American Idiot Broadway spectular.
