This is one of those songs that sneaks up on you.  It’s from a play called, The Man of La Mancha.  An old fella ( who has kinda gone crazy) decides to go on a quest.  He wants to right things that are wrong, and make the world a better place.  Unfortunately, he’s so old he does not realize that his dream is rather difficult to have come true.  It’s a wonderful play.  I won’t tell you how it ends, but this song is the song most people remember about it.  Contemporary artist, Luther Vandross, does a fantastic version of it.  It starts out real slow, so give it a bit.  It’s worth it, I promise.  We all have impossible dreams.  And as soon as we give up on their coming true – BAM!
