Things to do this week in London?

My friend and I currently have this week off from work and require things to do to occupy our free time, Therefore i was wondering if anyone knows of anything interesting, fun or sociable to do around the London area. Just to narrow down the scope of things a little here are a few things we enjoy

Live Comedy

Museums/Tours or learning experiences that are interesting

Cars/Carshows

Music Gigs/Shows

Would like to go watch something in a theatre, so any play that isn’t too convoluted would be great

Something of a classical nature, a rendition of a classical musical piece or ballet or show

Just anything fun where one can socialise with bunch of people
