Further reflections on this.... My immediate response was to listen to stuff I'd perhaps thought of buying but wasn't that committed to.... Then I listened to some stuff I haven't heard for a long time. Now I've gone thoroughly off piste and caught some Icelandic weird jazz thing... that I didn't hate... but boy is this a great way to discover new things.
I've also been able to listen to Another Monty Python record, which my dad had on vinyl and I haven't heard in years..... Remembered some of it almost word perfect.
