Fun fact: I took a music business course taught by him at LA Valley College in 2003, fresh out of high school. Fascinating topic, and a very quirky, interesting guy, to say the least.
Saw him when they were with Frank Zappa (The Depot, now First Avenue, Mpls.) in 1971, doing things like making a two-man pyramid, juggling one ball between the two, etc. Flying Burrito Brothers were the warm up band. Somehow I've never been able to get my hands on the live "71 CD which would be a virtual rendition of what I saw.
