I’ve mentioned it on Sam’s Patreon, but might as well link to the full interview here too, or at least a PDF of it with some wonky editing in places. There’s some fun bits in there about touring with pre-MIDI gear that barely stayed in tune in the studio… (so definitely some similarities to Sam’s adventures 40 years later 
).
(my favourite detail might be the drummer’s use of multimeters on stage to dial in the right tempo on his CR-78…)
EDIT: Seems I’ve mentioned that here as well, last time we ended up in early 1981.
