I've now got a good source for Jamaican stuff from a pretty unlikely place to be honest (in the States), every time I order from them, which has been 3 so far, I've had a copy of Phillip James for $5. And that ken Lazarus "The record" - four copies now, $5 each. Reason being, Wide Awake was a big hit in Jamaica so no reason for it to be hard to find in that format.
The Glenn Miller situation is ridiculous. As you know, I collected Doctor Bird for ages and there are far rarer records on the label like The Skatalites/Jack Sparrow, both Johnny & The Attractions (though there's been 4 copies of I'm Movin On on Ebay in 3 months) etc etc. And theres areally great northern track by Patsy which I must send up if I can find it.
