“All the notes are different, but the feel of it and the rhythm of it gives that track an extra little kick”: Producer Mike Stock on the secret sauce in Rick Astley's biggest song, why Stock Aitken Waterman was never a 'hit factory', and new music

Mike Stock.

Incredibly, it's been 45 years since Bucks Fizz won Eurovision for the UK with Making Your Mind Up. Now, the band are back, and, having been re-invented as The Fizz, their latest line-up is celebrating with a new single produced by studio legend Mike Stock.

Stock, of course, needs little introduction, having been part of the songwriting and production triumvirate that also included Matt Aitken and Pete Waterman and crafted over 100 hit UK chart singles, achieved 13 number ones and – in 1987 and 1988 – single-handedly generated an incredible 27% of all the cash in the UK record industry.
