i'm planning on going to rota, but before and after this, my time is a blank slate. since most of my visits to london are sweaty, smelly and stressful, i would like some recommendations on what to do in order to make the most of the day. would you like to recommend me something to do/somewhere to go? of course you would.

- cheap, second hand music shop? so i can buy a casio and/or drum machine?
- good charity shops? full of good cd's?
- other good and generally wholesome things to do? live musics, film screenings, naked tennis?

swish.
