I think that must count as one of those mistakes that didn't matter until it was pointed out. Not only had I not noticed it (or what I now presume it was) but I read Ollie's marquee with some considerable confusion, and thought Richard was talking about having asked John Butcher to change the date of the concert. None of which made any sense at all really.
Having said that, I got quite confused this afternoon trying to work out why my payslips for April, June and October all had odd numbers on them, until I realised that the tax year is 3 months behind the calendar and not 4 months.
I think I might make it to both the events suggested next week (this and Alvin Curran on Friday). Certainly one of them. Look forward to seeing people there.
