Mono Dansettes sink, stereo systems *float*!
"A friend of mine who was a motorbike enthusiast, and who hadn't heard the album before, ran to the window to look outside to see if he could spot the bike going past."
Yeah, but that was over 40 years ago when your cheap hifi's newfangled stereo tricks were still likely to get it burned as an instrument of witchcraft.
(Joking aside, AFAIK, it was only from the late-60s onwards that stereo started to become common in consumer equipment, so am I right in assuming people back then probably *were* more easily fooled, or at least impressed?)
