There are obituaries in The Telegraph and The Guardian - which also has a recent interview by Sarah Crown
"It's behoven upon you to do the best you can with the abilities you have," [Porter] says. "You honour the existence of everything else by doing so. I know I can't write novels; I've tried. I know I can't write plays. I can write criticism, and gabble away on the radio, but the only thing I can really do with any degree of finesse is write poetry. So I do it."A critical appreciation of Porter's work and some recordings of him reading can be found at the Poetry Archive.
