Trust me, you don't want me to sing...
Think whales mating..

That good says he that has never heard whales mating. Either in the wild or any of the documentaries that have appeared on the telly over the years. Unless you count "Star Trek, The Voyage Home" where you'd whalesong from Grace and a bit from Georgie.
However they weren't mating at the time...
