"Always" is a popular song written by Irving Berlin in 1925, as a wedding gift for his wife Ellin Mackay, whom he married in 1926, and to whom he presented the substantial royalties.
Although legend (and Groucho Marx) claimed Berlin wrote the song "Always" for The Cocoanuts, he never meant the song to be included in that musical, and it was not. Thematically, it serves as a sequel to Berlin's earlier song "When I Lost You," which pertained to the death of his first wife Dorothy.
The song entered into the public domain on January 1, 2021.
