“Stories of Phil Spector’s gunplay mounted over the years, including his discharging a firearm while in the studio with John Lennon during the recording of his cover album Rock ‘n’ Roll, placing a loaded pistol at Leonard Cohen’s head during the sessions for Death of a Ladies’ Man, and forcing Dee Dee Ramone to play bass guitar to Spector’s specifications at gunpoint….The Ramones reportedly had to play the opening chord to the song ‘Rock and Roll High School’ for eight hours straight.”
