I just saw a post on Tony Wilson's nicely asymmetrical gravestone as designed by Peter Saville and Ben Kelly. it made me think of the great concrete headstone at Patrick Caulfield's grave at Highgate Cemetery in London. at the time I saw it I hadn't got a clue who it was for, but it is a great gravestone indeed. during my visit I did all I could to find Sandy Wilson's grave. unfortunately, though, I had no luck. it would've been interesting to see.
