There could be an undiscovered species on Earth unlike anything we’ve ever known. Not in the ocean, but the ocean itself! Its body spans thousands of miles; its heart beats with a one-thousand-year pulse. It could even have an immune system capable of annihilating all other life on earth.

Now, transferred and restored from the original 16mm film, this footage is available to Supertramp's legion of fans worldwide.
In July 2006, the original master tapes of the album 'Supertramp: Live In Paris' were rediscovered in the Northern California barn of the band's drummer Bob Siebenberg, along with video footage. The tapes were sent to Cups 'N Strings Studios in Woodland Hills, California, for digital remastering. The tapes were initially in bad technical shape, but were successfully transferred to a digital format.
The original idea was to feature heavily footage of Paris, adding a story in The Song Remains the Same. The sound was remixed by Peter Henderson and Supertramp's original sound engineer Russel Pope from the original multi-tracks.
