-----Siobhan Donaghy was born in London. She was discovered by former All Saints manager Ron Tom, who went on to manage Sugababes. The group was formed when Donaghy and Mutya Buena, while working together in a studio, teamed up with Buena's best friend Keisha Buchanan.
Manager Tom came up with the name "the Sugababies.” Within a year they were offered a record contract by London Records, but decided on the name Sugababes; not Sugababies.
Their debut single, "Overload,” was a top ten hit in the UK and was nominated for a BRIT Award for "Best Single. It was also a top five hit in Germany and New Zealand. The group co-wrote most of the tracks on the album One Touch, which produced three more top forty singles in the UK: "New Year,” "Run for Cover" and "Soul Sound.”
Donaghy has said she left the group because she never got along with Keisha Buchanan. Her replacement in Sugababes was Heidi Range.
She started writing music with the help of former producer Cameron McVey under the alias of "Shanghai Nobody,” an anagram of "Siobhán Donaghy.”
In March 2003, Donaghy released the 7-inch vinyl single "Nothing but Song. " For the release of her first commercial single in June 2003, "Overrated," Donaghy reverted to her given name. "It peaked at No.19 in the UK, and was followed by the single "Twist of Fate,” which was released in September 2003.
Donaghy's debut album Revolution in Me was released by London Records in September 2003, and entered the UK Albums Chart at No.117. Donaghy parted with London Records and recorded a second album independently which was picked up by Parlophone, part of the EMI group, which also bought the rights to Revolution in Me.
The album's title track, "Ghosts,” was released in February 2007 as a 12-inch promotional two-track single. The album, Ghosts, was also released in June 2007 and peaked at No.92.
In October 2011, several news outlets reported that the original line-up of the Sugababes would and were writing songs for a new album under Polydor.
