3AM / Thunderbirds

"Thunderbirds Are Go / 3AM" is a double A-side single by English pop rock band Busted. It was released on 26 July 2004 as the fourth single from their second studio album, A Present for Everyone (2003). "Thunderbirds Are Go" was not originally included on the album, having been written specificially for the 2004 film Thunderbirds, although it later appeared on a re-issue of the album in Europe. "Thunderbirds Are Go" was not released on an album in the United Kingdom until the release of the group's live album, A Ticket for Everyone, in 2005.

"Thunderbirds Are Go / 3AM" was Busted's last single to enter the charts, reaching number one on the UK Singles Chart. It was the 20th best-selling single of 2004 in the UK and also won the title of 2004 Record of the Year. "3AM" was later performed by Matt Willis during his 2007 solo tour. On 27 April 2010, both songs were made available as downloadable content for the Rock Band music video game series.
