Lennon or McCartney: Who Wrote That?

From the Across the Universe site, dedicated to The Beatles:

Being that the Beatles were a four-piece band, and eventually ALL of the members wrote the songs, it can be confusing for some listeners to know which Beatle's songwriting is preferred. I have compiled a list to the best of my knowledge of who wrote what song, but there are a few disputes, which I'll note. Also, if a song is not included, then it is not written by a Beatle, and you can find out who wrote that song by viewing the albums page, finding the album the song is on, view the track listing and see who wrote it. Collaboration songs will be noted here as well, but only the ones that were a "true" collaboration. Most of the songs have input from more than one member at some point, but I'll list who the dominant writer was.
