An music at a place of public religious worship "this would excempt not only the singing of hymns or other religious material at a religious service, but also the performance of a classical concert at a church" says the guidance....what of a church brass band concert etc? May be ok but the guidance does not add much.

As far as I am aware this guidance cannot overule the wording of the Act. The words of the exemption for places of public worship in the Act - or the extention of this to London - will make exempt from the licensing requirement any entertainment defined in Schedule 1 of the Act as regulated entertainment - including amplified rock-bands and brass bands.............
