To be fair I did put on Dave Sealey with his one man show "Stanley Holloway - With a little bit of luck".
This in my opinion is the exception to the rule.

Dave brought all his own props and didn't want PA. He set it all up and explained to me that he used background music to support his singing and to keep as near to the Stanley Holloway story as possible.

I wasn't really sure what to expect, but was totally amazed at the sheer professionalism of Dave. He told the story of Stanley Holloway in a way that was so refreshing and he drew the audience of about 60 people into his performance. When he started singing the songs, he played background music and I was absolutely gobsmacked at the power and quality of his voice. This was indeed a very top professional one man show of the highest order.

Dave is a top man who knows his own skills and uses props appropriately.

Here are a few pictures of the show.
