HI, I saw Jon a few times at the Ring 'o bells fok club in Bath. Absolutely loved him. I have his records on vinyl and one on a cassette. It is possible that the powers that be at Fellside Recordings have his masters asd i once communicated with them and as I recall they had other things to do at the time. Looking at their current catalogue, littered with many successful new artists it may be that these songs never see the light of day again.
One track is available for download at emusic, see link below. Don.t know if the cd is still available.
