Early career Doherty and three friends, Richard Sheehan, Eddie Thibodeau, and Mike O'Connell, began their musical career in 1956 with a band called the Hepsters. Two years later they disbanded. In 1960, still in Halifax, Doherty, aged 19, along with
Pat LaCroix and Richard Byrne, began a
folk group, called the Colonials.
Columbia Records signed the group several months later, at which time they changed their name to
the Halifax III.
The Mamas and the Papas In 1963, Doherty established a friendship with
Cass Elliot when she was with a band called
the Big 3. While on tour with the Halifax III, Doherty met
John Phillips and his wife, model
Michelle Gilliam. A few months later, the Halifax III dissolved, and Doherty and their accompanist,
Zal Yanovsky, were left broke in Hollywood. Elliot convinced her manager to hire them. Thus, Doherty and Yanovsky joined the Big 3 (increasing the number of members to four). Soon, after adding even more band members, they changed their name to
the Mugwumps, a
CBC Television children's show chronicling the "lives" of vessels in a busy harbour loosely based upon
Halifax Harbour. In 1999, he played Charley McGinnis in 22 episodes of the
CBC Television series
Pit Pony. In 2004, Doherty appeared on
Sharon, Lois & Bram's 25th Anniversary Concert special,
25 Years of Skinnamarink, that aired on
CBC on January 1, 2004. He sang two songs with the trio: "
California Dreamin'" and "
Who Put the Bomp?" One of his last appearances was in the Canadian TV series
Trailer Park Boys, Season 7 Episode 10 (season finale) as FBI Special Agent Ryan Shockneck. Filming was completed just shortly before his death in early 2007 and the end credits dedicate the episode to him. ==Personal life and death==
