"Out of a personal archive of hundreds of hours of taped transmissions, my favourite sequence is from an unusual mid-week broadcast by a station called Lightning, which seems to have been hi-jacked for one night only by a duo called the FMB Crew (it stands for Fucking Mind Bending).

"After about an hour of rambling, nursery-rhyme banter, ranging from the sinister and scatological to the nonsensical and outright indecipherable, the pair suddenly get possessed by a kind of free-associational delirium. The soundtrack is a particularly febrile mix of DJ Hype's "I Can't Understand It At All" into a wondrously zany X Project track, in which choirboy Aled Jones's innocuous chart smash "Walking In The Air" is warped into an anthem for the no-sleep raver speedfreak: we're walking in the air/while people down below are sleeping as we fly.

"It loses something in transcription: the intonation, the grain of the voice, the instinctual syncopation, the drugged slurriness. But I'm not taking the piss when I say that I rate this-- and a score more snatches of phonetic poetry plucked live'n'buzzin' from London's pirate airwaves --among my favourite "cultural artefacts" of the Twentieth Century." --Simon Reynolds
