"Two in a Million" is a song by British pop group S Club 7, released as the third single from their debut studio album, S Club (1999), on 13 December 1999. The single was released as a double A-side with "You're My Number One" in UK, but in other countries, it was issued as a stand-alone single. The single debuted at number five on the UK Singles Chart and peaked at number two in January 2000. In New Zealand, "Two in a Million" became the band's third consecutive number-one single, after "Bring It All Back" and "S Club Party". Single information "Two in a Million" is described as "a song about falling in love, having somebody to comfort you, and someone to be there for you no matter what." The song sees Jo O'Meara taking sole lead vocals for the first time. The album version of "Two in a Million" and the Boyfriends & Birthdays version (so named as it was the theme song of their BBC TV movie) are almost exactly the same, except the Boyfriends & Birthdays version has slightly more robust instrumentation, taking on a more orchestral and R&B approach, and pauses the music during the last line of each verse right before the chorus. The latter is included on the North American version of 7. Moreover, the demo version of the song, as heard on Miami 7, includes horns in the arrangement, which were removed for album release and replaced with a more subtle French horn arrangement alongside the live string orchestration in the Boyfriends & Birthdays version. The single includes an exclusive B-side, "We Can Work it Out", which was performed during episode eight of Miami 7, "Alien Hunter". The track was again co-written by Mike Rose and Nick Foster, who wrote "You're My Number One". The UK release of the single includes the Miami 7 version of "You're My Number One", while the Australian release replaces this with the Jason Nevins remix of "S Club Party". The US release opts for a completely different B-side, containing an exclusive club mix of "Two in a Million" by Mark Penchotti, which has never been released elsewhere.
