"Only You" is a ballad written by musician Vince Clarke. He recorded it in 1982 after forming the duo Yazoo with Alison Moyet.
An a cappella version by The Flying Pickets was even more successful than the original on the UK Singles Chart, being released towards the end of the following year and becoming the Christmas number one in 1983. It spent five weeks at the top. This made "Only You" the first a cappella chart-topper in the UK, and was released on overseas markets the following year. The description of "a cappella" is misleading however, as synthesizers feature throughout the recording.
The Flying Pickets version went on to become a number one hit on the German Singles Chart in 1984 and charted in Canada as well, though it saw no chart action in the United States.
