Anyone listen to this already?

It's been around for a few years, since his centenary in 2012 in fact. See here.

Both Peter O'Loughlin and Seán Potts had been working on compiling collections of recordings of Tommy Potts for near on two decades and much of the material has been bouncing around among musicians. eventually RTE released this material. The RTE CD is a lovely collection.

FWIW, you'll find more of his playing on the lp 'The Gathering', from the eighties.
