Heres a somewhat strange, yet enchanting performance from a 1979 episode of the Muppet Show. The guest performer was Crystal Gayle, and the song is "We Must Believe In Magic." I find the song hopeful, in a strange mystical sort of way.
Mad is the captain of Alpha Centauri
We must be out of our minds
Still we are shipmates bound for tomorrow
And everyone here's flying blind
Oh, we must believe in magic
We must believe in the guiding hand
If you believe in magic
You'll have the universe at your command
Mad is the crew bound for Alpha Centauri
Dreamers and poets and clowns
Bold is the ship bound for Alpha Centauri
Nothing can turn it around
Oh, we must believe in magic
We must believe in the guiding hand
If you believe in magic
You'll have the universe at your command
La-la-da-da-da-da-da-da-da-da-da
La-da-da-da-da-da-da
La-la-da-da-da-da-da-da-da-da-da
La-da-da-da-da-da-da
Oh, we must believe in magic
We must believe in the guiding hand
If you believe in magic
You'll have the universe at your command
La-la-da-da-da-da-da-da-da-da-da
La-da-da-da-da-da-da
La-la-da-da-da-da-da-da-da-da-da
La-da-da-da-da-da-da
Oh, we must believe in magic
We must believe in the guiding hand
If you believe in magic
You'll have the universe at your command
La-la-da-da-da-da-da-da-da-da-da
La-da-da-da-da-da-da
La-la-da-da-da-da-da-da-da-da-da
La-da-da-da-da-da-da
Oh, we must believe in magic
We must believe in the guiding hand
If you believe in magic
You'll have the universe at your command
We must be out of our minds
Still we are shipmates bound for tomorrow
And everyone here's flying blind
Oh, we must believe in magic
We must believe in the guiding hand
If you believe in magic
