Ok, so I’m wrong
As reported yesterday, there was an ad in the FT listing 4,000 musicians who supported retrospective term extension. If you read the list, you’ll see that at least some of these artists are apparently dead (e.g. Lonnie Donegan, died 4th November 2002; Freddie Garrity, died 20th May 2006). I take it the ability of these dead authors to sign a petition asking for their copyright terms to be extended can only mean that even after death, term extension continues to inspire.
