I've found an interview with Jem Finer where he describes the process behind the Longplayer composition, and you can hear the music in the background. The 5 minute piece can be accessed as a RealPlayer stream via this BBC Radio 4 Front Row page (near the bottom).

I wonder if there should be a verbal equivalent whereby the word is preceded by a 'O'.

This would remind people of the oral tradition which many say is in danger of being lost - similarly placing the word in a broader context.

Obvious examples might be 'oshit', 'obollocks'.

My favourite would be 'ono' (no disrespect to Yoko).
