"The Fountain in the Park", also known as "While Strolling Through (or Thru') the Park One Day", is a song by Ed Haley, a member of the vaudeville act the Haley Brothers.[1] Some authors believe the song was written by Robert A. Keiser, to whom Haley dedicated the song.[2][3] The song was published in 1884 by Willis Woodward & Co. of New York, but dates from about 1880.[4] It is best known for the lyric "While strolling through the park one day, in the merry merry month of May," and has been featured in numerous films, including Strike Up the Band (1940), in which it was sung by Judy Garland.
As early as 1938, Shep Fields and his Rippling Rhythm Orchestra recorded the song as a Swing Jazz fox trot entitled In the Merry Month of May for Bluebird Records (#B-7606, 1938) featuring the young concert accordionist John Serry Sr.[5][6]
Bing Crosby included the song in a medley on his album 101 Gang Songs (1961)
