The clubs used to have a foot in both Ray's camps, usually combining a "professional" guest with unpaid floor singers. I put "professional" in inverted commas because these were not necessarily making a living from it, and could be fairly local singers offered the opportunity of an extended spot. The requirement to entertain the audience tended to encourage at least minimum standards of performance.

These days the clubs seem to have polarised and more seem to fall into one or the other camp.
