Hmm ... the Evening Standard is giving away tickets to see "The Tease Show," about which it says:

"The UK’s most spectacular revue, The Tease Show, returns in all its diamond-encrusted glory to London hotspot Koko from the 11-14 May 2009; bringing with it a tantalizing dose of old-fashioned glitz and glamour. Starring international showgirl superstar and the undisputed queen of British burlesque, Immodesty Blaize, the show back following a sell-out debut in 2008 will once again be compèred by the master of innuendo, Julian Clary."

I realize it would be a non-standard way to celebrate our anniversary (that or Giselle?), but it does sound like it would be a load of fun!
