Most musicians look back on a particular moment that set the ensuing decades onto a new path for them.

Perhaps a song played on the radio, a new LP in a friend's collection, a live performance - out of the blue and always life-changing in more or less subtle ways. With me it came in a record shop in Bath when I was 15 or 16, quite young enough for new enthusiasms to arrive like steam locomotives.
