This interview was recorded right before a soundcheck on a tour with the band Bruford in 1979, relatively recent after Allan Holdsworth's depature from the Bruford band (references are made to his replacement John Clark).
Bill talks about his experience with U.K. and the band Bruford, among other things. He makes numerous references to Allan throughout.
