Elton John (in his first U.S. show), Linda Ronstadt, Buffalo Springfield, Bonnie Raitt, Van Morrison … acts who owe their start to this intimate club read like a Who’s Who of classic rock. Lenny Bruce was infamously arrested on obscenity charges after a 1961 show, and John Lennon and Harry Nilsson were booted for heckling the Smothers Brothers in ’74. Established and emerging artists still treat audiences to memorable shows. All ages admitted.
