Yes Dave, I agree it was strange and I did query it, but they were pretty adamant at the time. I could understand/accept it being required for the equipment. No mention was made of PAT testing, but I guess this is probably in the PLI smallprint.
I suppose technically an individual DJ could do something to cause injury or damage (... I remember throwing a record into the audience at the Locarno, and saying "I wasn't playing that crap again - so don't ask me").
I'm sure insurance companies could come up with a huge, pedantic list of possible public liability claim scenarios.
I doubt it reduces Hotel insurance premiums one iota, so is yet another means of extracting more insurance client premiums.
Yet another bi-product of 'health and safety gone mad', in turn itself a result of 'litigation culture' - one of our less useful American imports.
