Jonny Trunk and Duncan Wisbey have stumbled upon a comedy goldmine with this musical presentation of fan letters written to British soft-porn stars. The mail was collected by Trunk, who ran a fanclub for his glamour-model sister. The music, and the characterful voices in which the correspondence is read, are Wisbey's. As directed by Alan Cox, their combination of squalid private fantasies and very actorly recital is often sublimely funny.
It's the detail amid the filth that's delicious, conjuring up surprisingly differentiated personalities. There's the fan with the over-enthusiastic punctuation, or the one whose scatological missives end with a polite: "Yours sincerely ... " There are the frustrated romantics ("I would also take you horse-riding and to see Barry White") and those whose fantasies are the more bizarre for not being remotely sexual.
The comic juxtapositions and turns of phrase are gloriously idiosyncratic. "Charmaine, I have just sent £15 for your pussy hair. But I forgot to send my address." What turns this into gold is the contrast between Trunk's low-key narration and Wisbey's flamboyant vocal and musical skills. The latter impersonates Michael Caine, Kenneth Williams and Cary Grant to bring the fanmail to life, to the keyboard accompaniment of some saucy seaside backing track or, for the climax, a rhapsodic Handel-esque aria.
Seriously arousing stuff.
