Is this a 1976 release? It is on this site, but I've seen on a couple of other sites 1977 quoted.
My usual sources (AMG, Amazon, AM, Wikipedia) all say 1976.
Thanks. Rate Your Music had it as 1977, I've submitted a correction there.
It would appear all those sources are wrong, it should be 1977: http://www.roots-archives.com/release/322
Or that source is wrong. Although it seems rather reliable.
