Ace were a British rock music band, who enjoyed moderate success in the 1970s. They are notable for their part in the early career of Paul Carrack, who later became famous as a solo artist, and as a member of several other groups. The band was formed in December 1972 as Ace Flash And The Dynamos, but this name was quickly abbreviated to just Ace. Their most popular hit was "How Long", which featured Paul Carrack on lead vocals, about some prominent members leaving the band.
