グラム・パーソンズ
Hillman quit the Byrds within a month of White joining, in order to form the Flying Burrito Brothers with Gram Parsons. At around this same time, White and Gene Parsons undertook some informal rehearsing and recording with Hillman and Gram Parsons, as part of a prototype version of the Burrito Brothers. However, the pair declined an invitation to join the new country rock group and instead opted to stay with McGuinn's new-look Byrds.
