I forget who clued me into this, but it was someone on Twitter.
The website begins, "On Sept. 9, 2009 I experienced something that I still am having trouble believing happened to me. I came into the possession of a cassette tape containing a Beatles album that was never released. I dont expect you to believe what happened to me, I sure wouldn't, but thats why I grabbed the tape as proof that my experience was real."
The download links to a series of remixed "songs" consisting of snippets of Beatles tracks and solo tracks mixed together to make it sound a little as if the band were still making music. It clearly took a lot of effort on someone's part. I haven't listened to all of it yet, but I have found it interesting and somewhat enjoyable.
If you're a Beatles geek like me, go grab it before it disappears. (I can't imagine someone's not going to get sued over this.)
