Doctor JohnI was led aa month or two ago to the following site, www.rockinworld.com. (Maybe one day I'll learn how to imbed a URL so you can just click on the blue letters. I do have the little HTML instruction site bookmarked.)
They sell used CD's and LP's by mail. Despite their URL, they list many folk titles (folk is listed as a separate category).
I checked just now, and they list one Tony Rose LP, "Under the Greenwood Tree." They have two copies for sale. I do not know how often they update their list.
I used them once to purchase an obscure album. They ask collector's prices. It is not a bargain bin. I was pleased with their service.
Enjoy the music!!
