According to Malcolm Macfarlane's Bing Crosby Diary 1940-1949, Crosby provided music for Cecil Stokes (1910-1956) for several Auroratone films used in mental hospitals by the US Government.
According to Macfarlane:
Jun 22/23, 1944
Crosby recorded three songs ('Going My Way', 'Ave Maria' and 'Home On The Range') with Eddie Dunstedter at the organ for use in an Auroratone film. The films were used in Army and Navy hospitals in the treatment of neuropsychiatric and severe migraine cases.
