I might be tempted to pop to this.
I say 'pop', it's a bit of a trek, and last time I went to a London meat I got a wee bit lost & then almost couldn't get home cos the bus driver said I was drunk!
Just checked my rota (I'm at work) & I'm actually free that weekend, so mark me as a maybe.
May need prodding if I forget to post on here for a while again.
