I had a dream once that was identical to this commercial, except it was a meerkat instead of a donkey, and it was "Take My Breath Away" instead of "In the Air Tonight."
I once had a job interview very similar to this one.
John Cage was one of the 20th century's greatest composers, and this is greatest work. I have heard the piano version, but I like the orchestral version better. Please watch the video all the way to the end as the commentary is very helpful.
