I'm not much of a fan of The Beatles but I did think this sounded quite interesting, since it's been done by Mr Martin - it seems to be a real attempt to do something worthwhile on the part of Martin.
On Radio Five last Friday they played a tiny bit and discussed it. There was also a short interview with George Martin. Click on the link, select 'Friday' and then fast-forward about two hours five minutes (I think) to hear, if you like.
edit: forgot the link, ha ha:
