[Dixielandjazz] gospel tunes

Dear Scott,
This one intrigued me, as it it not on the general list of Hoagy items 
I have.
The best I could come up via the internet (apart from the ubiquitous 
ads) is that it is from the 1950s and conprises Hoagy's lyrics set to
the 18th variation from Rachmaninoff's Rhapsody on a theme by Paganini.
Is this true?
It is on the CD set 'The Hoagy Carmichael Centennial Collection', but 
not in the Index to Mr Sudhalter's book 'Stardust Melody".
Is there a story behind it?
Kind regards,
Bill.
