"If that is all you care for your heritage you are rootless."

Not at all. My earliest memories are of my mother singing music hall songs (she was born in a zepellin raid), probably learnt from her mother. There were a sprinkling of traditional songs in there and lots of 1930s MGM musical ditties. My 'heritage' is blues, soul, rock and folk via popular music radio and concert going, which I consumed indiscriminately until discrimination showed me they blurred marvellously and I could no more be a sharecropper than a ploughboy.

Plenty of lovely old songs with personal experiences laid over vicarious and imagined ones until they form a palimpsest of history, their provenance defined and re-defined in my own window of time. Far more important than the individual meat pies of someone else's taxonomy.
