This is digression, and no relation to Ebbie's lyrics, but the name "Maiden's Prayer" has been used since 1850 (see American Memory for sheet music to these pieces). It was a very popular piano piece by Badazewewska (words added later by Adams, and variations by Paul), and guitar piece by W. L. Hayden.
Guest Gladys asked for a 'waltz' called the "Maiden's Prayer;" I would guess that there is a waltz setting somewhere.

Johnny Gimble, the Texas fiddler, recorded a fiddle tune called "Twilight Waltz," sound clip here: Music Outfitter
