Launching in the middle of the rock legends The Beatles' career in 1966, Micky Dolenz, Peter Tork, Michael Nesmith and Davy Jones (who was the only Brit in the all-American group) starred on their eponymous NBC comedy until 1968. Post-TV career, the group continued to record albums. In February 2012, Jones passed away from a heart attack at the age of 66.
