"Who Would Have Thought" is a song written by Darren Hayes and Guy Chambers, for Hayes' third solo album This Delicate Thing We've Made, released as a limited-edition 7" vinyl and digital download alongside the "Me, Myself and (I)" single release. Hayes added an animated video for the song as a teaser on his official website, as well as his Myspace profile, on 9 April 2007. The single failed to chart due to its ineligibility as a promotional release. The b-side "The Only One" is included on the album This Delicate Thing We've Made.
