Chantey Cabin had several copies of the Phil Tanner CD (No: VT145CD) "The Gower Nightingale" at the Mumbles Maritime Festival which is where I purchased it. If you are going to the Sea Fever Festival in Hull this weekend you might be lucky to get it from the Chantey Cabin.
I also treasure the 1968 LP of Phil Tanner produced by The EFDSS of recordings made by the BBC in the 1940's. All the songs are included on the new CD.
