The Last Unicorn is a movie inspired by the book but remember it's also a 1982 soundtrack album composed, the song has been covered by Kenny Loggins on his Return To The Pooh Corner album I'm sure that's the other reason this film was easily formed with unique music.
When the last eagle flies over the last crumbling mountain, and the last lion roars at the last dusty fountain. In the shadow of the forest though she may be old and worn, they will stare unbelieving at the last unicorn. When the first breath of Winter through the flowers is icing, and you look to the north and see a pale moon rising, And it seems like all is dying and would leave the world to mourn, In the distance hear the laughter of the last unicorn. I'm alive, I'm alive. When the last moon is cast over the last star of morning, and the future has passed without even a last desperate warning, Then look into the sky where through the clouds a path is torn. Look and see her how she sparkles the last unicorn. I'm alive, I'm alive.
