Its a fine balance and I've found the best clubs are a mixture of some savvy commericial acumen (after all , what's the point of putting on a turn if no one's in the audience) AND a knowledge and respect for the tradition. The purist clubs were always a bit "eat it up its good for you" for my taste, even 30 odd years ago, before the disillusionment with the left. These days the hardline traddy purists seem anachronistic. I appreciate what they do, if only some of them wouldn't take it so seriously and rear up at the merest hint of professionalism.
