Cover art for Sassafras Roots lyrics by Green Day

I remember reading somwhere that Billie Joe wrote this about a girl he used to date before he met Adrienne - some girl who went off to join the Peace Corps or something. Can anybody verify?

Yes, it's the same girl who he wrote "She" about. She left him to go to Ecuador for the Peace Corps and wrote him a feminist poem also entitled "She" when she broke up with him. The song "Chump" is written about the guy she left him for.
