"enjoy sparking off each other"

Sounds as though they're early for the Blitherscrum Erotic Fest which, of course, is not until Octember (according to the publicity leaflet I found in the bus shelter and had to carefully peel from the wall).

As a sweetener the Committee are sending two free tickets for the Saturday night Concert to Oliver Truffles and his partner Porcine O'Sercha. They have also sent some of the boys round to the Anagramatists to "tell them their future".
