Which Lennon song began as the Beatles-era composition 'Child of Nature'?

The Lennon song that began as the Beatles-era composition “Child of Nature” was “Jealous Guy.”

Lennon wrote the original composition in 1968 after the Beatles attended a lecture by Maharishi Mahesh Yogi in Rishikesh, India. Paul McCartney drew on the same subject for “Mother Nature’s Son,” while Lennon’s related song was titled “Child of Nature.” Lennon recorded a home demo at George Harrison’s Esher house, but the Beatles did not include the composition on The Beatles, commonly called the White Album.

The song resurfaced during the 1969 Get Back sessions under the working title “On the Road to Marrakesh.” Lennon eventually abandoned the original lyrics, although he retained much of the melody. In 1971, while making Imagine, he rewrote the song as a personal confession about jealousy, insecurity and the pain those feelings caused. The new version became “Jealous Guy.”

The common mistake is treating “Child of Nature” as an alternate title for the released song. It was an earlier lyrical and thematic version, not a Beatles release; “Jealous Guy” appeared on Lennon’s 1971 solo album Imagine.
