The Spin Doctors came by the Rolling Stone studio recently to celebrate the 20th anniversary of their album Pocket Full of Kryptonite by performing that record's two biggest hits and a cover of Robert Johnson's blues classic "Stop Breakin' Down Blues," which was made famous by the Rolling Stones. After the set, the guys reminisced about writing their hits and explained how they dug up rarities for the reissued version of the album.
