Eighteen months on, here's that list again:

Maddy Prior and Tim Hart: Summer Solstice
Watersons: Frost and Fire (and others)

And in those eighteen months I've caught up with...

Albion Country Band: the Battle of the Field

Which is an absolute corker, it has to be said. Could be subtitled "In which Ashley and friends invent folk-rock without really thinking about it, and do it properly".

Still, only one album out of 20+. I'll have to step up my acquisition rate if I'm going to get through the list.

(I was reminded of this thread by the sight of a copy of New Victory Band's One More Dance And Then (which nobody mentioned) in the Manchester Oxfam shop. Muckram Wakes plus Pete and Chris Coe! Very tempting, even for someone who prefers songs to tunes, but the condition of the vinyl was just too dodgy.)
