I saw this last night, and would highly recommend it.
Anyone else seen it? It was very educational, made me pretty excited about Welsh/South American history. And it looks lovely, it's pretty funny, and reminded me I should go back and listen to all my SFA albums. And try buy lots of stuff by Rene Griffiths.
Tip: don't go to a Q&A if you do get the chance. Gruff seems like a lovely man, but is painfully inarticulate. There was a lot of awkward silence while he tried to form sentences.
