Also, there are quite a few songs from the Beatles catalog that are not included on the disc, but will be available for download. "All You Need Is Love" is available now, with 100% of the proceeds going to Doctors Without Borders.
Abbey Road (1969) will be available October 20th,
Sgt. Pepper’s Lonely Hearts Club Band (1967) will be available in November, and
Rubber Soul (1965) in December.
"Strawberry Fields Forever" was only released as a single, so they may sneak that one in at any time in between the above mentioned, or after. I think that eventually we'll see all of the Beatles songs available for download, as well as some of the individual Beatles' solo efforts that came afterward.
