John Lennon wrote "The Continuing Story of Bungalow Bill" about Richard Cooke, a hunter he met at the Maharishi's camp in India. Cooke hasn't shot anything since the camp, except with his camera - he became a freelance photographer for National Geographic.
Jay-Z's 2012 "Glory" features his daughter Blue Ivy Carter's cries and coos. At less than two days old, she became the youngest ever credited artist to feature on a Billboard chart when the song debuted on R&B/Hip-Hop Songs at #74.
"Abracadabra" was inspired by Diana Ross and The Supremes. Steve Miller first met the girl group when they performed together on NBC's Hullabaloo in 1966, and he wrote the lyrics after spotting Diana Ross skiing in the mountains years later.
