Entertaining is not always about 'getting a cheap laugh', Dick, or getting any sort of laugh if it comes to that. Entertaining can be tugging at the heart strings. Telling an amazing story. Dazzling people with your skill. Many, many different things can be entertaining. Yes, you do need to get the balance right but with the best will in the world, if the artist does not entertain me in some way, I am not likely to pay to see them again!

I like Buddy Holly songs BTW - Even though they were a bit before my time. His music was simple and very entertaining. I cannot honestly say the same of Cliff Richard but I know that plenty of other people would. Not saying that either is suitable for a folk club but the simplicity of Holly's music certainly lends itself to audience participation and I have never objected to anyone playing it :-)

Bit of a tangent though so I'll leave that bit of the thread there!
