S&r, read uk.music.folk as well. One report over there is:

Saw him playing at Wakehurst Place Craft Fair, Ardingly,
West Sussex last weekend.

Seemed glad to still be on this planet.

Playing quite well. I personally thought his technique was not up to
his previous standard - unsurprising only 5 months after major heart
surgery.

Good at least to hear he is out and about.
