The Viscounts were an American pop group from New Jersey, formed in 1958. They had one hit single, with Earle Hagen's instrumental classic "Harlem Nocturne" in 1959, which peaked at #52 in the U.S. Billboard Hot 100 chart in early 1960; it was re-released in 1965 and hit #39 the second time around.[1] The single and album of the same title were originally recorded for the Madison label, then both were reissued in 1965 on the Amy label, the Amy LP having a slightly different track listing than the Madison release.[2][3][4]
