Thanks for posting these stories LEJ. Regarding the Burritos making the first recording of Wild Horses I'd heard that the Stones sent a tape of it to L.A. and had Sneaky Pete put a pedal steel track on it (which apparently wasn't used in the Stones release) and the Burritos heard and cut it.
You're right Bartholomew, Chris Hillman deserves his due. He co-wrote some great tunes with Parsons and did much of the singing after GP split from the group. And wow! Byrds, Fleetwood Mac w/PG and Muddy in one night.f
