Have sent you a PM rjp, but if they're gone then I'm definitely on the look out for a spare.I'll be travelling up from the Northants area, so could also help with a lift up, but not back as I'll be getting the boat home after.
I can't make it now so have 2 tickets going free to any h&v member that joined before this message was posted. If you're quick I can post them 1st class otherwise you'll need to collect from Leicester or catch me at Birmingham airport on Friday evening.
