Bob,
Sorry I haven't got back to you, I haven't been able to get in touch with my brother (he's on holiday) to confirm he's ok with it.
I'm going away tomorrow for 6 days, so it will be the end of next week before I can confirm.
Don't want to mess you about, or keep you hanging on, so if you sell the tickets before then, then we'll look elsewhere.
Cheers
Andy
