In 1988, when Astley was soaring up the charts, I was working midnight-dawn shifts at the local radio station. So I got to hear way too much Rick Astley. But I noticed something fascinating: if you play a Kylie Minogue 45 single at 33, it doesn’t sound “a bit like Rick Astley”, it IS Rick Astley. Understandable I guess, given they are both creations of the Stock Aitken Waterman production team. I began to think there was no way of proving what I was saying, but then I discovered this on YouTube. The presenter is speaking German, but you get a good demonstration of the effect.
