Hi Lee, just had a look in Discogs, and they have it as 1986, ditto the Alligator reissue of Dr. John's GUMBO which was the LP before it. 1986 would certainly tie in with the "licensed from WEA" credit, as WEA got the international rights to MCA in 1983 or 1984 (and MCA had the rights to this because the original albums that this was complied from were on ABC, which MCA bought in 1978/79). I think I might still have some late-80's Schwann catalogues from the US at home, so they may help to pin it down a little more, but I don't have any Aussie catalogues from the period, unfortunately.
Can't date this one but it a came through MCA most likely mid 80's, the record was originally released in US on Alligator but surfaced here on this mysterious label. Anyone out there with catalogues that can help pin this one down?
