"Truly Madly Deeply" is a song by Australian pop band Savage Garden recorded between 1995 and 1996, released as a single in 1997. Written by bandmates Darren Hayes and Daniel Jones, the song is a reworking of an older song of theirs called "Magical Kisses" and was the third single from their self-titled debut album.
The Japanese release, available elsewhere on import, was actually a special, album-length disc comprising 14 rare tracks, featuring three versions of the title song, along with three bonus remixes, six rare B-sides and two acoustic live versions.
There are two distinct versions of the song. One was released on the Australian album release, whereas the other version was on the US release. This version composed in 1996 features a drum-machine track instead of the more acoustic-sounding music in the Australian version. The US version also featured on their 2005 greatest hits, Truly Madly Compeletely. Both versions have been played on Australian radio; the US version now being the more popular.
