At the Steve Hoffman Music Forum, there is a post from "Steel Woole" about Green Manalishi:
Manalishi backing tracks were recorded at Western Recorders Studio 2, 6000 Sunset Blvd., Hollywood, CA on January 8, 1970 on four of sixteen available tracks.
Engineers listed on the tape box are "M. Birch/HBD"

I never read/heard of this exact date before, thought some of you here might be interested!
