The tune, which will be released on iTunes Dec. 2, was penned by composer J. Ralph, who has collaborated with the likes of Norah Jones, Ben Harper and Carly Simon, in addition to scoring films including "Finding Vivian Maier," "The Cove" and "Man on Wire."
"I was delighted when J. Ralph first told me he had written a song with me in mind and when I heard it I new he meant it," Minnelli told The Huffington Post in an email statement. "It reminded me of some of the best songs I've recorded over the years."
Calling Minnelli's talents as a performer "unrivaled," Ralph added, "When the director first showed me his film, I instantly heard Liza singing this song over the final scene. She delivered a masterful, effortless performance and is one of the sweetest, most sincere people I have ever met."
