Actually musicians can be prosecuted under this law. Jamie Cullum was right first time (see The Times 13 Jan 06).

If you organise a licensable gig in an unlicensed venue, you are in the firing line. This is no different than the old regime.

In 2002 Westminster City Council prosecuted a singer who organised a regular gig in the basement of a hotel. She ran these as a private members music club. Westminster also prosecuted the hotel owner. Undercover council officers gained entry to the club on the night without the then 24 hour registration period. I know about this because I helped the singer, Lee Lindsay, prepare her some of her defence.
