Speaking of the Red Sox

I hate most recordings of "The Impossible Dream (The Quest)"

normally sung by some middle-aged lothario (Elvis, that means you) bellowing in long sustained notes, backed by strings, and a halleujia chorus.

Talk dreadfully misinterpreting a song.

Don Quixote knows that he is not really Don Quixote but an impotent old man.
Don Quixote realizes that his death his near, that we die alone, and is terribly afraid.
Despite this, he acts as is he is brave and has faith. In doing so faith and courage are given to him

The movie gets it right, mostly on the strength of the sad, sunken eyes of Peter O'Toole.
