What's a good investment these days? Stocks? Gold? No, how about the handwritten notes Paul McCartney made for the recording of the Beatles' classic "Hey Jude?" Julien's Auctions sold the lot on Friday for $910,000, more than 5 times the estimated value of $160,000 - $180,000. As you can see here, there are photos from inside London's Trident Studios showing the band using these very notes.
