Nah, I'm with Steve on this. A bunch of musical poseurs. 20 minutes was more than enough. Life's too short.
BUT - the audience seemed to enjoy it, as did the above poster, so good luck to them. Just not for me. I had hoped for better when I came across the programme by accident.
Oh - and I hadn't heard of Oliver Cromwell banning musical instruments from being taken in to pubs/inns/taverns. Where did that come from ?
