I am not really into posting recordings on Soundcloud, especially of other people whose permission I do not have to do so. Copyright is a funny thing: if I take a photo of a performer, I own the copyright, but if I make a tape or video the copyright rests with the performer (or his/her estate I am guessing) and also potentially whoever else may have publishing rights over the material performed if it is not original (so no Paul Simon, Ralph McTell or other songs/tunes without their owners' permission...)
Nonetheless, I can share the two tunes with you or other interested parties via dropbox if you send me a PM or a message via Facebook, or email me at tonyrees49 (at) gmail.com . I guess it's really up to Ralph's estate to decide whether and what to post of his work publicly, and I am more than happy to send them the files.
Cheers - Tony
