Some early info here, courtesy of Trembling Bells Facebook page:
Saturday 19 August
Shirley Collins: 18:00 Main stage
Alasdair Roberts: 18:45 Walled Garden
Trembling Bells: 20:15 Walled garden
Given that Alex Neilson (and possibly some other Bells) are playing with Shirley Collins and Alex is drumming for Alasdair's trio that's a hell of a turnaround!
Alasdair followed by the mighty Bells in the Walled Garden - sublime.
