A friend just emailed me this - the boys have done a cover that features on a double album of John Lennon covers called "instant karma" - a project put together by Amnesty International in aid of the refugees in Darfur.
This tells you about the record and the crisis:

You can also buy the track through there as an MP3 download.
Also Amnesty have released a funny video interview of them talking about the track and the whole porject, as well as some footage of them recording in the studio:
