Jealous Guy

In an unspecified parallel universe, Fitz Kreiner had encountered a song by the Beatles that had what Trix MacMillan said was the same tune as "Jealous Guy" with different lyrics.

The song began with:
 * ''On the road to Rishikesh
 * ''I was dreaming more or less

(PROSE: The Gallifrey Chronicles)

Behind the scenes
In the real world, "Jealous Guy" is a song released by John Lennon soon after the breakup of the Beatles. The tune was originally composed in 1968 with different lyrics and a different title - "Child of Nature" - but for reasons unknown, the song never made it onto a Beatles album. The original lyrics (available here) begin with the same couplet that Fitz provides in the novel.
