Blue Horizon is correct. The B side of the JS "Linda" single has an "unavailable elsewhere" version of TD, it's a studio cut presumably made at the same time as the rest of the tracks on the selftitled JS solo album on Reprise from 1970 but for whatever reason was left off of the JS solo album, and NOT the Boston Tea Party FM version.
There seems to have been MANY albums related to early FM stuff called "Blues years" but from the way the thread starter lists it, it sure sounds like the Tea Party version that is on the BY album in question (to me anyways).
