Owing to a certain inconvenient popular event taking place on Saturday, viz. the Eurovision Song Contest, we have decided to postpone our party until 17th May.
Apologies for any disturbance in your schedule. We hope you did not rush unnecessarily to prepare a suitable costume. Not that you need one. Clothes of some decent sort are all that is required, but if you wish to wear spangly tights, a walrus moustache, and flippers, feel free.
