Records, owned by Lawerence Livermore who was in a band called the Lookouts! with a drummer named Tre Cool, who would become Green Day's drummer in 1990.

Billie Joe Armstrong, Mike Dirnt, and Tre' Cool.
Jason White is not a member of the band Green Day. Jason plays with them during live shows so Billie Joe can move around and have a little more freedom when singing, but he is not a formal member. He does, however, play in Billie Joe's side band Pinhead Gunpowder with Billie Joe.
