This compilation album with songs performed by Hoagy Carmichael is named after his biggest hit: “Ole Buttermilk Sky”, a song with lyrics by Jack Brooks that was nominated for the Academy Award for Best Original Song in 1946. (The prize was awarded to “On the Atchison, Topeka and the Santa Fe” by The Harvey Girls).
The Bold weight of Volta, released a few years before by Bauer and available in the US as Fortune, is used for the title and artist’s name.
