they still have a "Selkirk Sessions" weekend in early October which has effectively kept the whole thing and the music going: no concerts or booked artists, but a weekend of pub sessions.

They do? I thought it folded. Most of the pubs in Selkirk have closed, and this site

was last updated in 2014.

I think I've been twice and it was good back then.
