I learned the song from Dave The Ancient Mariner, and he related this story to me about Rita....It seems she took a tour of the Capr Breton Mine Musuem and was so taken, she wrote this song shortly thereafter......I admit her version is a bit too hectic for me, but I slowed the "tango" tempo down a bit and I love to sing it....It flows so beautifully....I do it in Eb........Frank ofToledo
