Technopicker - Adrian Legg.
1981? 1982? Or 1983? I was invited to a pub where Adrian Legg was demoing Ovation guitars. My reward was a single malt and cascades of notes, including those formed by having his guitar fitted witn banjo tuners which employed stops - so allowing all manner of alternate tunings and pseudo pedal steel riffs in the middle of a piece. All of this was punctuated by the patter
and an occasional dusting of talcum powder on his hands. It's still one of my favourite live music experiences.
e: also, he smoked a pipe.
