The wife and I (plus eldest) are going to Edinburgh on the 23rd and the wife is performing! She's not doing comedy as such but is part of something called 'A Pint of Poetry & a Dram of Drama' at Scotland's most haunted pub, The Banshee Labyrinth.

She'll be on sometime between 13.10 and 14.10 and could well be performing her latest piece, a rather nifty ditty about sexually transmitted diseases*.
*Will probably have to block our daughter's ears for that one!
