Peter Tork, bassist and keyboardist for The Monkees, died on Thursday. He was 77.
In 2009, Tork 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 Tork left the band later that year. 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.
Dolenz tweeted on Thursday that his heart is "broken," and Nesmith said he is "clinging to the idea that we all continue," but the "pain that attends these passings has no cure."
