This john song, with stream of consciousness lyrics, has a world wildlife fund version featuring wildlife sound effects. It is Across the Universe.

"Across the Universe" is one of the few songs John is proud of. The Beatles and his fans around the world are stunned at Lennon's  incompetence to acknowledge his own genius, citing his rejection of his favorite song.

However, it is the critical self-assessment that has been proven to guide the artist to the perfection of his work. It's easy to say about John Lennon. John claimed that unconscious inspiration was the source of some of his songs, but his description of the inspiration for "Across the Universe" might sound divine .

Lennon said about Across the Universe in 1980: “The words are purely inspirational and were given to me – except for maybe one or two where I had to resolve a line or something like that”.
