I have a copy M-, of course backed with the brilliant 'Lost Love'. It would be £50 all in if you wanted it. Paypal (personal/gift). No worries if not John
'Constellation' is one of those labels that has various designs for their releases, I've seen at least 3 different designs for Dee Clark 'That's My Girl'!!
Just got a Capitol set off there. Cheapest going but postage is fairly high. Listening to the Alexander Patton track propelled me to buy, fabulous record and worth the money just for that one.
I have that Buster 45 in my collection, great soul number.
Mathis also did one called 'Come Back' which I know has had some plays on the Popcorn scene.
