I've been quite into 4 channel quadraphonic format (the precursor to surround sound) for a while and I read that her track "Easy Evil" was the only one from her album "Cameo" to be mixed into such and included in a sampler album (as Howes would put..), but online, there's not much abundance of further information about the inclusion of her track into a particular sampler album outside a comprehensive Dusty discography book, let alone actually listening to a sample track of it. Perhaps the Dunhill sampler album was not well selling?
The quadraphonic format has been revived not long ago, though not as significant because, well, Dolby 5.1 or 7.1 Surround is now the industry standard for most audiovisual applications.
I think Geffen or whoever holds the rights to her ABC/Dunhill tracks, ought to have the tracks remixed into the old quad, or 5.1 for the DVD/Blu-ray audio if the Cameo multi-tracks are still around, but I figured it would be a bit of a niche since multi-channels aren't a norm in music listening.

What are your thoughts?
