This is a cover of “Birthday”, that originally appeared on Icelandic band The Sugarcubes' debut album, Life’s Too Good in 1988.

Björk, the lead singer of the sugercubes as quoted in Martin Aston’s Björkgraphy:

It’s a story about a love affair between a five year old girl, a secret, and a man who lives next door. I was always changing my mind about what the lyrics should be about. I had the atmosphere right from the start but not the facts. It finally ended up concentrating on this experience I remembered having as a little girl, among many other little girls’ experiences. It’s like huge men, about 50 [years old] or so, affect little girls very erotically but nothing happens … nothing is done, just this very strong feeling. I picked on this subject to show that anything can affect you erotically; material, a tree, anything.”

The Sugarcubes' first international single, released on the small indie label One Little Indian, the single blew up after Chris Roberts named it Single of the Week in the UK music weekly Melody Maker.
