Keep it Peel at Maida Vale

[festive50@...]

Has anyone on list been to any of the sessions at Maida Vale?
Somehow, by sheer fluke, I've got an invite to the Keep it Peel gig and in
invite it says "Security have asked us to remind you that cameras are not
allowed inside the venue".
Is this a strict rule and are camera phones allowed, or do they frisk you
for them?
Also, only just discovered, it's being shown on BBC4 live.
