Other guests included Kit Cox (who did a stand-up comedy set), Andrew O'Neill (who was MC for the evening), a couple of Elvis impersonators, Lady Raygun on the steel drums*, various other actors and musicians and even Mr Robert Rankin himself.
Archimedes the Steampunk Parrot was in attendance too and really got into the groove, as you can see here.
You can see some photos of the event here.

* I've never heard 'I Gotta Feeling' played on the steel drums before, or 'Birdhouse in your Soul', but they sounded great!
