The two "leaders" on our part in the Lords are Baroness Buscombe and Lord Redesdale. You might also try Baroness O'Neill of Bengarve, who is a sympathiser but did not support the last exemption in the Lords because of drafting concerns - as likewise others. Lord Monson is another possible.

I may also point out that the "churches" exemption includes all places of public worship - of any religion - (by which I think I mean recognised religions so don't start silly ideas about Jedi Knights or founding religions that happen to run folk clubs, or worship beer). Accordingly if there were any religion that was likely to rectuiting terrorists, or threatening to invade events at the places of worship of other religions, the "church" exemption might very well also exempt some nasty activities. I also view goverment concerns about events organised by corrupters of youth with some cynicism, in the context of the church exemption, given the record of organised religion in such regards. But I am doubtful whether arguments based on such premises would be well received!

I would however point out that the thrust of the latest ACPO letter may add to the argument that acoustic music should be wholly exempt - acoustic versions of "Cradle of Filth" songs are rare indeed, as are goths at folk clubs - not that I would mind either, in moderation (mustn't drive out too many traddies) but if the argument is that metal corrupts, so gigs must be policed, then gigs that are not metal do not need to be policed.
