I happened to stumble on this today - not sure how long it's actually been available, but I thought there might be some here who might be interested...

Digital download of the full-length (6:39) 12" Mix of Q-Feel's "Dancing In Heaven (Orbital Be-Bop)"
From my limited research, it appears this version has never been released on any commercial CD, and in fact, has only been on the Mexican and Canadian 12" singles, released in 1982. Feel free to correct me if any of this is wrong.
Sound quality is excellent, with full dynamic range!
