Does anyone know what happened to members of the duo Martin Carter and Graham Jones?

Graham played a fretless bass.

They did the folk clubs in the late 70s. This included Orpington when it was at a pub in Green Street Green. There were about 8 people in the audience and when they got up to play there were 6.
Then a guy in a brown anorak got up and left leaving 5! Martin dedicated a song to the 'man in the brown anorak'.

I guess with gigs like that, they gave up???
