Tony Engle came down to a meeting of the Tradsong Forum when it was at C# House a couple of years ago. What he said was basically what Vic said. IE., that Topic would be looking to release the more economically viable material. Hopefully, and knowing Tony, that means anything which won't reduce Topic to the financial equivalent of a smoking ruin.

For the rest, I don't think Tony was thinking solely of Musical Traditions, although Rod is clearly a major candidate. It would be a case of anyone who was looking to release the stuff and was presumably willing to pay a modest price for the rights.

Just an afterhought. A number of tracks from the three cassettes I mentioned were included in the Caedmon-Topic Folksongs of Britain series. The original VOTP omitted anything which had gone out on Caedmon, presumably because the rights had been bought by Rounder, who were in the middle of their own massive Alan Lomax reissue programme.

Whether that would apply now with the new VOTP, I know not.
