Paul Revere, the organist and leader of long-running classic rock band Paul Revere and the Raiders, died on Saturday in his Idaho home, the band’s official website confirmed in a letter. He was 76.

TMZ reports that he has been battling cancer since last year, though no official cause of death has been announced.

The Raiders got their start in 1963, when they released their cover of Richard Berry’s “Louie, Louie.” They would go on to release four Top Ten singles in the ’60s: “Hungry,” Good Thing” “Him or Me, What’s It Gonna Be” and, one of their biggest hits, anti-drug song “Kicks.”

In 1971, the Raiders released “Indian Reservation (The Lament of the Cherokee Reservation Indian).” The song became their biggest hit, hitting No. 1 on the Billboard chart in July 1971 and selling more than one million copies.
