Question: who wrote hello, goodbye and i am the walrus?

<P0-S0> Boy Meets Girl: Say Hello to Courtship is a 2000 book by Joshua Harris. <P0-S1>  It is the sequel to "I Kissed Dating Goodbye". <P0-S2>  In "Boy Meets Girl", Harris describes his personal experiences courting the woman he eventually married. <P0-S3>  The book argues that psychological pain and trauma can result from entering an intimate relationship before one is ready, either emotionally or financially, to commit to being the other person's life partner. <P0-S4>  Margaret and Dwight Peterson wrote an essay called "God Does Not Want to Write Your Love Story" in which they criticized "Boy Meets Girl", among other books. <P0-S5>  In this essay, the Petersons expressed "how different these stories of romance are from any traditionally Christian understanding of marriage." <P0-S6>  Harris has written several other books, including "I Kissed Dating Goodbye", "Sex Is Not the Problem (Lust Is)", and "Stop Dating the Church". <P0-S7>  "Boy Meets Girl" did not receive as much critical attention as "I Kissed Dating Goodbye". <P0-S8>  Leah Andrews of the "Lewiston Morning Tribune" compared "Boy Meets Girl" to Eric and Leslie Ludy's "When God Writes Your Love Story", suggesting that both texts are popular Christian books providing alternatives to dating. <P0-S9>  Andrew Dalton of the Legion of Christ wrote that he was partway through reading Anthony Bannon's "Peter on the Shore" when he became distracted with "Boy Meets Girl". <P0-S10>  In 2000, Rebecca St. James anticipated using her song "Wait for Me" to promote "Boy Meets Girl". <SEP> <P1-S0> "I Am the Walrus" is a song by the Beatles released in November 1967. <P1-S1>  It was featured in the Beatles' television film "Magical Mystery Tour" ("MMT") in December of that year, as a track on the associated British double EP of the same name and its American counterpart LP, and was the B-side to the number 1 hit single "Hello, Goodbye". <P1-S2>  Since the single and the double EP held at one time in December 1967 the top two slots on the British singles chart, the song had the distinction of being at number 1 and number 2 simultaneously. <SEP> <P2-S0> Clarence Wainwright Murphy, also known as Charles William Murphy, C.W. Murphy and C. Murphy, (1875–1913) was a prolific British composer of music hall and musical theatre tunes, perhaps best known for the song "Has Anybody Here Seen Kelly? <P2-S1> " with lyrics by Will Letters (1908). <P2-S2>  In 1926, "Has Anybody Here Seen Kelly?" <P2-S3>  was made into an animated short of the same title directed by Dave Fleischer, and in 1928 into a feature film directed by William Wyler. <P2-S4>  The song was also performed in the 1943 film "Hello Frisco, Hello". <P2-S5>  With frequent collaborator Dan Lipton (1873–1935) he also wrote "My Girl's a Yorkshire Girl", mentioned by James Joyce in his novel "Ulysses" and also turned into a 1909 short sound film of the same name. <P2-S6>  Another song, "Little Yellow-bird", (aka "Goodbye, Little Yellow Bird") written with lyricist W. Hargreave, can be seen performed by Scottish comedian Charlie Naughton in the 1938 film "Alf's Button Afloat" and by Angela Lansbury in the 1945 film "The Picture of Dorian Gray" and again by Lansbury in the 1985 episode "Sing a Song of Murder" from her TV series "Murder, She Wrote". <SEP> <P3-S0> "Hello, Goodbye" is a song by the English rock band the Beatles, written by Paul McCartney and credited to Lennon–McCartney. <P3-S1>  Backed by John Lennon's "I Am the Walrus", it was issued as a non-album single in November 1967, the group's first release since the death of their manager, Brian Epstein. <P3-S2>  The single was commercially successful around the world, topping charts in the United States, the United Kingdom, Canada, Australia and several other countries.
