The Doors experienced a bit of a resurrection in the early 80's, particularly in the UK.
Bands like Siouxsie and the Banshees listed them as inspirational and so their albums were re released and sold well.
I've been to the Perre Lachaise cemetery in Paris when Morrison is buried - there are many other famous people buried here too.......Oscar Wilde, Bizet, Proust to name a few.
