Ersatz the way to do it!

I was at the Lichfield Garrick watching Growing Old Disgracefully in the Studio this weekend. In the main theatre was John Hylton with Real Diamond. He is apparently Europe's foremost Neil Diamond tribute performer.

Tribute bands and acts are not my favourites, I must be honest, but any live show that gets people into a theatre has to be a good thing. Now I can understand people going to see a tribute act but why would you buy a DVD of a tribute act? Why not just buy a DVD of the act they are a tribute to?
