Monkees lead singer and OG teen idol Davy Jones died this morning from a heart attack, confirms his rep. Jones was the very dreamy breakout star of the late sixties made-for-TV boy band the Monkees, who brought you classics like “Daydream Believer,†“Stepping Stone,†and “I’m a Believer.†You may also remember him as that guy who took Marcia Brady to the prom. He was 66.
