"Again" is a popular song with music by Lionel Newman and English lyrics by Dorcas Cochran. It was first heard in the 1948 film Road House, directed by Jean Negulesco, in which Ida Lupino sings it. An instrumental rendition was later used in Pickup on South Street (1953).
The original hit recording is by Vera Lynn, backed by Bob Farnon's orchestra. It was recorded in July 1948 and released by London Records in November 1948, and it reached the Billboard Best Seller chart in January 1949. By 1949, versions by Vic Damone, Doris Day, Tommy Dorsey, Gordon Jenkins, Art Mooney and Mel Tormé had also charted. Later recordings by Ricky Nelson, Dinah Washington, The Four Freshmen, Nat King Cole, Pat Boone, James Brown and Mark Murphy followed.
