Good for you John - can't say I've played my copy in over 30 years though! Track B5 is a beauty, and one I've got on the back of Patsy's 'We Were Lovers' 45 on the same label.
If memory serves correct, this might be one of those Trojan LPs with a 'swooshing' sound throughout. 'Brixton Cat' is another, although that's more of a squeek. Might sound ok in mono though?
