Though Sonja Kristina is credited as the sole lyricist of "It Happened Today", in a series of interviews conducted from late 1998 through March 1999, Francis Monkman claimed to have conceived the song's title and basic lyrical concept.
He explained the inspiration for the song's music: "I was a great fan of Terry Riley (having played in the 1st London performance of "In C" in 1968) and was very impressed by A Rainbow in Curved Air.
Then I had a kind of "musical vision" of a high-energy rock sound going into a Terry-like tape-loop improvisation.
Martin recalled that their collaboration on the song was so tight that often each melody was produced alternately by first one composer, then the other.
One other song was recorded and released only on singles: Though Rob Martin is credited for bass, he had already left the band due to a hand injury prior to recording, and Sonja Kristina revealed in an interview that Francis Monkman played all of the bass parts on the album.
