Three key players in 1960s pop music died last week

Tony Sheridan, George (Shadow) Morton, and Kevin Ayers - three relatively unknown yet key players in the history of 1960s pop music - all died last week. Sheridan was the bandleader who taught the Beatles the ropes in Hamburg, Germany, and has the distinction of being the only non-Beatle to appear as lead singer on a Beatles recording. Shadow Morton was the writer and producer of the Shangri-Las' number one hit, "Leader of the Pack" and Janis Ian's "Society's Child". And Kevin Ayers was the mastermind behind Soft Machine, an influential underground band during the first wave of experimental jazz-inflected pyschedelic rock.
