No, when I recorded them, there were five people in the group:
Clarence White - guitar, vocals
Roland White - mandolin, vocals
Billy Ray Latham - banjo
LeRoy Mack - Dobro
Roger Bush - bass
They were the house band at the Ash Grove in L.A. for the Sunday jam sessions. I became pretty good friends with Leroy, Billy Ray, Roger, and, of course, Clarence. I often picked up Roger Bush and his bass in El Monte to take him to the Ash Grove in L.A. whenever his car wasn't working.
Later, I renewed my friendship with Clarence when he joined the Byrds. since I was associated with the Byrds at the time (i.e., living off of my song royalties).
