And then there was the year our upstairs neighbour let his flat to some bloody arty farty drama lot. (Rumour had it they were they Footlights but I cannot confirm.) Neighbour had refurbed the flat when he bought, including sanding and varnishing the floor boards, and moving the kitchen from the back of the flat to the middle of it.
This was all fine when it was just him living there, but there were quite a few folk in the group, none of whom seemed to have any experience of removing their shoes when in the flat. So we heard every footstep...
That was annoying enough, but they were using the large livingroom as a place to sleep, and gathered in the kitchen late at night after coming back from performing/seeing shows. They liked to play guitar and sing off-tune, and then there were the fucking bongos in the small hours, in the kitchen that was right above our bedroom.

We (well, dh) spoke to them nicely, they "forgot" and carried on carousing nightly. Eventually we broke, hammered on the ceiling with brooms, buzzed their door entry and screamed. It was not a happy summer.
None of the fuckers seem to have become famous, though, and none of the fuckers ever handed over the wine they "intended" to use as an apology, either.
Bastards.
(That was cathartic.
