It's 5 or 6 years since I last looked into this.

Latest development is a retro Little Golden Records cult collectors site
that has digitised the tracks for Itunes..

and a couple of various artist compilation CDs on Amazon

[needle drops of old poor quality novelty undersized colour vinyl 78's???]

But it don't look like any complete Roy Rogers' and Dale Evans
Little Golden Tones recording sessions available on CD ?

Wonder if the master tapes survived ???
