It is hereby announced that Oxy's semi-final of Mastermind is now apparently on Friday 2 April on BBC 2 at 8 p.m.
Unless they change it again - it was originally not till 7 May. A check on the listings (I'm doing Henry VIII) will show it nearer the time.
Coincidentally, the Herefordshire/Worcestershire lodge is planning an evening of drinking and petty one-upmanship in a pub in Worcester the following Wednesday (or possibly Tuesday), so this would be the ideal chance for you to fall in wondering adoration at my feet/ridicule me mercilessly [delete where applicable].
