I well remember Mick from my time at University in Cardiff (1977 - 1981) and his contributions to the folk scene around South Wales.
Calennig always did an entertaining set, as did his other band the four-piece with Siwsan George and (was it Stuart Brown?) as well as Mick and Pat.
I recall the first time I saw Jim Couza, who came along to Whitby Folk Week along with Mick's band.
I wish Mick a good recovery and a speedy one.
Geoff Gilday.
