Season 4, Episode 17 The Graduate.
This is another case of the song listed in the soundtrack for the episode is different. I just re-watched the season on netflix (the songs that they used here are different than how they originally aired) and would love to know what this song is. It from the 40th minute of the episode and is the last song.
"Twinkle Twinkle Little Star...how beautiful you are...shadows.. You shine for everyone."
It's a haunting variation of the original. Your help would be appreciated :)
