I spliced together videos of my two trips to Sipadan, Borneo - including that awesome video sequence of swimming through the Barracuda Tornado. And mated it with the music from the group Celtic Woman. The song is "Beyond the Sea". If I remember correctly its based on an original French song entitled, "La Mer" (The Sea), by Charles Trénet.
The sea was indeed like a mirror when we cruised towards Sipadan - this effect was real and not photoshoped.
