Great to find this thread! I have searched for info on Lawrence since I first got internet access in the 90's, with very few hits. This is a treasure trove! I saw him perform several times at Freight and Salvage and bought Coyote's Dream when it came out. I actually bought several copies (4, I think) and gave some away.
It is nice to see that I am not the only one who wished to have a recording of Little Britches. I also love his rendition of John Deere Tractor. Someone above pointed out that the Judd's version is slowed down and that is certainly true. They are great singers, but LH just did it so much better!
In all my searching, the most interesting thing (prior to this thread) I found was an article in the San Francisco Chronicle about Bob Weir of The Grateful Dead. Turns out he was a half brother to James Louis Parber of the Whiplash band. The whole story is here: https://www.sfgate.com/entertainment/article/Weir-finds-his-birth-father-and-adopts-a-vintage-2778049.php There is also a letter to the editor regarding the Weir article from LH's brother and another from one of James' brothers.
