Peter Tork, bassist and keyboardist for The Monkees, died on Thursday. He was 77. In 2009, he was diagnosed with adenoid cystic carcinoma, a rare cancer affecting his head and neck. Known for their hits "Daydream Believer" and "I'm a Believer," The Monkees had four No. 1 albums and a television show that ran from 1966 to 1968. The group, comprised of Tork, Davy Jones, Micky Dolenz, and Michael Nesmith, released the movie Head in 1968, and later that year, Tork left the band. He participated in several reunion tours, both before and after Jones died in 2012. Tork's last solo record, "Relax Your Mind," came out in 2018.
