Tamara - I'll send your message to the editor of the Old Time News, the magazine of Foaotmad here in England - I know he's a fan of Derroll's from way back, and I reckon he'll put it in the mag. if that's OK with you. One of our readers could help. The other place to write to would be The Old Time Herald - the US magazine that everybody in the Old Time music world reads. Their website's Here.
Cheers
Ray Banks
Chairman of Foaotmad)
