Writing about music whilst dancing to architecture, playing saxophone and hang-gliding

Chris Kilsby drew my attention to this poem in today's Guardian (a newspaper). Chris makes reference to writing about music as being equivalent to dancing about architecture. 

It's an oft quoted remark that has been sourced to many and denied by most which is understandable given the absurdity of the latter statement.

One listens to music and comments subjectively. Likewise, one dances to music but usually without commenting on the building ("Do you come here often to this 19th century building that was once the home of the visionary architect John Dobson?" "You do? Then you'll have noted the facade with its quaint Corinthian pillars that was so typical of the 1920s, It really is one of the city's architectural gems. I've got a book that tells you all about this city's architecture. Whoops, sorry, I've stood on your toe. By the way, may I see you home?" "Ah well, nice dancing with you, sorry I stood on your toe"). Lance
