If you aren't familiar with the band Oasis, they were a British rock band that formed in 1991. Two of the members, brothers Noel and Liam Gallagher, could NEVER get along and left and rejoined the band numerous times.
Back in 2010 after Oasis had called it quits, the Oasis box set Time Flies was released, with all of the group's recorded material, as well as bonus DVD commentary from Noel Gallagher. Listening to his commentary shows that Noel hasn't really lightened up at all in recent years and that he seems to have hated every minute of being in that band.
Despite being completely pissed off the whole time, it's some of the funniest commentary we've ever heard!
