Final answer:
The title and lyrics of John Lennon's song 'Mr. Kite' were inspired by a 19th-century circus poster advertising a performance featuring someone named Mr. Kite, which was a part of Pablo Fanque's Circus Royal.
Step-by-step explanation:
The title of John Lennon's song "Being for the Benefit of Mr. Kite!" which is often simply referred to as "Mr. Kite," comes from a 19th-century circus poster advertising Pablo Fanque's Circus Royal. The poster announced a performance in which Mr. Kite was to appear. John Lennon came across the poster while filming a promotional video and found inspiration for the song from its phrases. The song is featured on The Beatles' iconic 1967 album Sgt. Pepper's Lonely Hearts Club Band. Lennon incorporated many of the specific details from the poster directly into the lyrics.
