The fiddler was Martin Lynott, not Terry Walsh, and I've never heard about any "... spreading rumours ...".

After the Beggarmen split, Terry and Tony Kelly went out as a duo, and used to alternate with myself and Al Lawrence in running sessions at the MSG, before its demise.

I believe Martin is one of the residents at a session on Mondays at the Oddfellows in Middleton - see http://www.folkimages.com/Oddfellows.htm. I'm not sure if it's still in operation.
