Backing track borrowed from youtube. I sang lead and backup vocals. I'm not really a big Green Day fan, I just thought his vocal style was similar to mine and wanted to try it. I think I did a respectable job.
Originally recorded by Helloween I found the karaoke on YouTube Played by Alex Titoff http://www.youtube.com/watch?v=iy6rNrXBSZo&feature=share&list=UUvNr0w3zpb7mHavCvINxfLQ
