Dwelt in, quite a few. SLEPT in, only one.
   About 1980, while living in London, I went down to the Copper family's club in Peacehaven. Pub hours were quite strict 40 years ago it went on far too long & at a certain stage, even with dimmed lights, there was a rat-tat on the door.

    Bob was concerned, as the man in charge, and hushed everybody before answering the door to a couple of policemen!
    The club was full, and we all kept very quiet. I'm not sure how he managed it, but they left & we all breathed again.

Any other course would have been quite serious for Bob, and he cleared the club fairly quickly- most folk were local, so sneaked out the back way! We were driving & planned to go back to London, & Bob said that wasn't wise, so we spent a night on the floor in front of a lovely log fire.

I saw John Copper at Dartmoor about 2005 & he was delighted to meet someone who had actually been at the club lock-in, which seemed to have entered local folklore!
