Career
Sheehan was perhaps the most experienced musician in the original lineup of Boston. He had been gigging with his dad since he was 5 years old and majored in vocals at the New England Conservatory Of Music. He dropped out of school to pursue a professional musical career.
Sheehan met Sib Hashian and that led to his role playing bass in Boston shortly after the band signed a recording contract in 1976.
After leaving Boston, Sheehan (along with two other ex-band members) sued Tom Scholz, before settling out of court. After leaving the band, Sheehan made several guest appearances, including Hallelujah with Sammy Hagar and The Waboritas.
Sheehan no longer plays professionally after he injured his hand in a biking accident. On February 25, 2012, Sheehan played with Boston bandmate Barry Goudreau on stage outdoors for a three-hour benefit concert in Florida at the "All Star Jam for the Sydney and Berne Davis Art Center in Ft Myers Florida.
