Starship founder Paul Kantner came up with the term "Planet Earth Rock and Roll Orchestra", a label of reference to the San Francisco musicians that played onDavid Crosby'sIf I Could Only Remember My Name. During the sessions for Crosby's album atWally Heider Studios, the musicians of each band (who were working in other rooms) dropped in to the sessions and improvised hours of music, and everything was recorded. Some of the basic tracks played during these recorded sessions in 1971 were used for Crosby's album. Engineer Stephen Barncard and David Crosby made rough mixes of some of the session tapes, and in 1991 Graham Nash sent a DAT tape to Paul Kantner which later showed up in the tape trading markets as a 'pristine' digital copy. Barncard came up with the PERRO abbreviation when he needed to identify the 2 inch wide tapes on sides, standing vertically.
