I rented this 1 hour 38 minute dvd from Netflix released in 2005 titled Caballe: Beyond Music. I read her autobiography awhile back, so it was fun to see the places she had written about. About 3/4's through, there was a five-minute collage of her work with Freddie - part of their Barcelona and Golden Boy performance, and there is a small clip of him talking about their collaboration (all of which are on his solo dvd.) Caballe's life, once she became an "overnight " sensation, was one of elegance and lavishness, and she kept to her tradition of unwavering dedication to music. This is a rich film. That the best opera singer in the world did an album and performances with Freddie is another recognition and tribute to his genius and talent.
Yes, it was a worthwhile experience.
