Songfacts®:

• Speaking to Mojo magazine September 2012, Ray Davies explained regarding this single, "I was expecting my second daughter, Victoria, and in that song is all the layers, the cathartic feelings, the problems, the images, my thoughts on my position in the world, why I should be a parent… I called it 'Wonderboy' because I didn't know it would be a girl."
• Despite being a favorite of John Lennon, the song stalled at #36 in the UK charts, becoming the band's first single not to make the UK Top Twenty since their early covers. However, Davies remains philosophical about its relative failure. He told Mojo: "It wasn't a great hit but that doesn't matter. That work is out there. Writing songs is like running a marathon; the important part is finishing."
