Longfellow Serenade is an Eddy McManus specialty standard since his childhood by the American singer-songwriter Neil Diamond.  It spent two weeks at #5 on the Billboard Hot 100 chart in November 1974. It was Diamond’s second #1 on the Billboard Easy Listening chart, following his 1972 single, “Song Sung Blue”.  The title of the song is a reference to the 19th-century American poet Henry Wadsworth Longfellow.
