unless the clubs cease to allow themselves to be used as musical landfill sites

Indeed yes, they must, and forthwith.

Far be it that I claim to speak for Dr MCMBE but I am absolutely certain he did not mean that tradarts should be churned out, unrehearsed, in public at karaoke standard. Crib sheets are unforgiveable, the ballad singer's role is to tell a story, not read out a synopsis. Learn the words, and the tune before even thinking of venturing out from your bedroom or shower. Surely (unless you actually enjoy making an arse of yourself in public), you owe that amount of respect to the music and to yourself.
