yes, 1981 release. rca didn't have such unlimited access to the (merkin) laurie label in '75 - it would have appeared on laurie in the states, and on philips in the uk (and prob'ly elsewhere in yeurrp), through about 1978 - indeed, 8/16 tracks did appear on the 1975 merkin laurie lp of the same title, though not tracks a2, 7, 8, or b2, 4, 5, 7, & 8 above.
Cover images added. Back cover features a useful discography. All tracks are original mono recordings.
I question the 1975 date for this, the original Laurie US LP was released in 1974, but back sleeve of this shows 1981, though that may be a date of new album artwork. A 1975 version would have orange labels - so if anyone's got one, let's see it!
The printer code at bottom right on back is C/7/81 - RS.
Would RS be Robert Stace?
