I didn't see a thread on this, forgive me if I've missed one.
Radiohead have a recorded a new song in memory of the last survivng British WWI veteran who died on the 25th of July at the age of 111.
Here's the BBC report
featuring the song although I'm not sure whether nor not you can listen to it outside of the UK.
If you want to download it, follow the link in the article above, I think there's a link there and the proceeds go to the Royal British Legion.
