Dispensing with all the usual Valentine's Day kitsch, Museum Of London has decided to host an alternative V-Day bash. Technically it's the day before, but whatever: the point is you can enjoy live music from the Trans-Siberian Marching Band, all 13 of them. There's also bohemian artwork, a Chalkboard Philosophy workshop and an absinthe masterclass. You've never experienced a night at the museum like this. Over 18s only.
