Originals: Jealous Guy by John Lennon (covered by Luna)
So John Lennon makes his second appearance in this series - he'll be back when we reach the Rs for 70% of a track.
Jealous Guy started out as Child of Nature, written after The Beatles attended a lecture by Maharishi Mahesh Yogi, and demoed at Harrison's home in Esher in 1968.
The track never made it onto a Beatles album and was rewritten as Jealous Guy for Lennon's Imagine.
Luna recorded the track for Noah Baumbach's 1997 film Mr Jealousy
