One Voice is the sixth studio album by singer/songwriter Barry Manilow, released in 1979. The title track was featured in a lengthy segment in an episode of the British comedy show Only Fools and Horses, "Fatal Extraction", where the show's central character Del Boy starts singing the song outside a block of flats late at night after he's been drinking, starting a riot.
