Copyright
Donaldson established his own publishing company in 1928, and his rights in the song were apparently assigned to his company at that time, with the song listed as having been published by George Whiting Music and Donaldson Music.
The song was subject to copyright in 1925 and 1927. These copyrights were renewed in 1953 and 1955, after the death of both composers, at which time the rights in the song were owned by Leo Feist, Inc.. The rights were thereafter assigned to the EMI Catalogue Partnership, controlled and administered by EMI Feist Catalog Inc.
