I just got the Collectables version of these two dates in the mail (from The Bastards™), and am really diggin' both dates. And it's one of the better Collectables issues I've ever heard.
Funny, three tunes from the Oliphant date with Green and Patton also show up on Patton's Got a Good Thing Goin' -- two originals "The Yodel" and "Soul Woman" (supposedly co-authored by Green and Patton, cited as such on both the BN date, and the Atlantic), along with "Ain't That Peculiar".
Which date was recorded first?? I would maybe guess the BN date (29-Apr-1966), but the Collectables issue just says "released in 1967" - with no recording date listed.
Funny how more than half of that BN date (3 out of 5 tunes) appeared on two different albums, all within the same year.
