Before they begin, Rivers Cuomo tells him "I remember New Year's 2000, you called up my band Weezer and you said 'Guys, come on up and open for my band in San Diego' and that was a big break for us, man, because we were in oblivion at the time. So you gave us a big boost and it's great to have you up here with us." See the video of this event below:
