Avant de Mourir / My Prayer
The song was originally written as an instrumental piece with the title “Avant de Mourir” by Boulanger and first recorded by Orchester Georges Boulanger in 1924. English lyrics were added by Irish songwriter and lyricist Jimmy Kennedy* in 1939. Glenn Miller and the Ink Spots had large hits with their 1939 recordings, but the most commercially successful cover was that by The Platters, recorded in 1956.
Avant de Mourir
Georges Boulanger — While many date the composition 1926, Second Hand Songs gives the date of the first known recording as April 1924, a recording by Orchester Georges Boulanger. Second Hand Songs appears to indicate that it was released as the B-side of the single Natascha (Russische Weise) (VOX 01530).
(below) This may be a copy of the 1924 recording, but the Youtube provider calls it “the original,” yet gives no recording date, performer credits, etc.
(below) The image used by the video creator suggests that the recording is an undated Telefunken issue. However, the recording is not precisely identified by the provider, who leaves it undated. It’s significantly different from, though similar to, the recording in the video above.

In France “Avant de mourir” was featured in the Casino de Paris spectacle “Amours de Paris”  starring Maurice Chevalier. The title was changed to “Tout nous parle d’amour” (lit. Everything speaks to us of love) although another set of lyrics with the title “Ma prière” was written as well….
This version of Tout nous parle d’amour is performed by Orchestre A.J. Pesenti, a popular French tango orchestra during the late 1930s, according to the provider, recorded in 1939.
