Birthday

"Birthday" - written by John and Paul, and featured in "The Beatles" (aka White Album). Not to be mistaken with "Happy Birthday", which is a cover of the traditional birthday song by the Beatles.
This song is also a link that is often included in birthday wishes in Facebook. So if someone sent you a link to this page, "Happy Birthday!" to you. :D

Revolution

"Revolution" is an anti-establishment song written and sung by John Lennon. The song, though about wanting a revolution, is against achieving it through violence though. From the B-side of the "Hey Jude" single, released in 1968.
Note the "shoo-bee-do-wah" that was removed from the single in this particular version.
