"Several species of small, furry animals, gathered together in a cave, and grooving with a Pict" Mike Oldsfield, "Tubular Bells" Album
It doesn't have to have hit Number One, but should have at least charted, as per Jan and Dean'c October 1964 effort:
The Anaheim, Azusa & Cucamonga Sewing Circle, Book Review & Timing Association... Then there's B-sides of charted tunes...when Prince's When Doves Cry went to No. 1, he became the artist with the longest title for the flip side of a chart-topping song. The B-side of "Doves" was 17 Days (The Rain Will Come Down, Then U Will Have to Choose. If U Believe, Look 2 the Dawn and U Shall Never Lose). That replaced the previous record-holder, the flip side of Nino Tempo and April Stevens' Deep Purple, titled I've Been Carrying a Torch for You So Long That I Burned a Great Big Hole in My Heart.
