No Reply (song): "No Reply" is a song by the English rock band the Beatles from their 1964 album "Beatles for Sale".  In North America, it was issued on Capitol Records' variant on the British release, "Beatles '65".  The song was written mainly by John Lennon and credited to Lennon–McCartney.  Lennon originally gave the song to another artist managed by Brian Epstein, Tommy Quickly, in June 1964, but Quickly decided not to use it.

The lyrics typify Lennon's more introspective and mature songwriting on the "Beatles for Sale" album.

Baby, You're a Rich Man: "Baby, You're a Rich Man" is a song by the English rock band the Beatles.  It was written by John Lennon and Paul McCartney, and released as the B-side of the band's "All You Need Is Love" single in July 1967.  The song was recorded and mixed at Olympic Sound Studios in London, making it the first of the Beatles' EMI recordings to be entirely created away from EMI Studios.  The track features a monophonic keyboard instrument known as a clavioline, which Lennon played on its oboe setting, creating a sound that suggests an Indian shehnai.  In its lyrical themes, the song addresses the "beautiful people" of the 1960s hippie movement and partly echoes the utopian message of "All You Need Is Love".  The lyrics have also invited interpretation as a message to the Beatles' manager, Brian Epstein.
