Writing about walking while listening

A couple of days ago, while glancing through 'Connect', the in-flight news magazine of SN Brussels airline, my eye was taken by an [anonymous] piece about the joys of walking round Stratford-upon-Avon while listening to Duke Ellington's Shakepeare-inspired LP of 1957, 'Such Sweet Thunder'. The bard and Sir Duke is certainly a sweet combination, although I'm not sure they fit quite as snugly as the author of 'Such Sweet Thunder's sleevenotes suggests when writing, "It is, of course, idle to speculate upon what might have happened if Ellington and Shakespeare had been contemporaries, but there is no doubt that Duke, who calls himself an 'amateur playwright' is a very professional showman. And there is no doubt that the bard had rhythm in his soul."
Nevertheless, it was great, at 27,000 feet, to see an article positing the combination of an interesting walk with appropriately interesting music. When, in the early 1990s, artists such as the KLF ('Chill Out'), Ultramarine ('Every man and every woman is a star') and Jah Wobble and Brian Eno ('Spinner') were throwing such ideas out of left field, I wonder did they think it would take a decade and a half before the notion would be mainstream enough to intersect with the world of the business traveller?
