The Impossible Dream (見果てぬ夢 for Japanese), it is a song from the musicalMan of La Mancha. I've often found myself humming this tune these days. Man of La Mancha is based on the story of Don Quixote by Cervantes. Would you like to listen? I thinkthis music video , a scene of the musical, is nice and I'll introduce another YouTube video with lyrics below. How do you like it? I feel nostalgia for the time when I went to see the musical with my mother. She loves musicals and I would accompany her. Now she is 90-year-old and wouldn't like to go out due to osteopolosis. We two love this song.
