Here's hoping someone knows a thing or two about Alvin Reid, producer / owner ? of the label 'One Heart'
I can't trace any info on this man or the label except four 7" singles came out at the same time years back on re-release, 'Evil People' - Bob Clarke / 'Version' - Peter Tosh and one other single plus the two listed below.
(A) I'll Take Your Hand - Alton Ellis
(B) I'll Take Your Hand Version
(A) Orthodox Rock - I Roy
(B) Orthodox Drums - Bongo Herman
(both these singles sound like they are based on Alton's Studio 1 gem 'Almost Anything')
Apart from that there seems to be no other details.
