One Voice is the debut album by Scottish boy soprano Andrew Johnston, who rose to fame in 2008 after his appearance on the second series of Britain's Got Talent.

Recorded in London, the album features both classical and popular songs, some of which had been previously performed by Johnston, including a duet with Faryl Smith.

Critics responded positively to the album, favourably comparing Johnston to Aled Jones, and One Voice was rated gold in the UK.

[1] Despite this, it was announced that he had been signed by judge Simon Cowell's label Syco Music in June, and that his debut album would be released in late 2008.

[2] It was on the show that Johnston first performed a rendition of "Pie Jesu", later described as "the song that made him famous",[3] as well as a cover of Eric Clapton's "Tears in Heaven".

[4] Both of these songs were recorded for One Voice,[3] and so was a duet of "Walking in the Air" with fellow contestant Faryl Smith, first performed on the Britain's Got Talent Live Tour.

[8] Writing for the United Kingdom's Daily Express, Robert Spellman said that "anyone missing Aled Jones since nature had its way will lap up Andrew's butter-wouldn't-melt renditions of Pie Jesu, Agnus Dei and One Voice.
