This song is from the movie Follow That Bird; please let me know if additional context is required.
When I was a kid, we had a bootleg soundtrack of this movie, made by recording all the songs from the video onto a cassette tape. Apparently I didn't listen to it often enough because when I watched the movie again last year, for the first time as an adult, I had no conscious memory of this song at all. I almost fell off my couch when I heard the music cue, saying to myself: "How is it possible that there's a Bert & Ernie song in this movie that I don't remember?"
As the song started playing, I started to feel a slight sense of recollection, a vague sort of sparking in the synapses. It was very faint, like the memory of a dream. Not the memory of a dream upon waking, but the memory of a dream from years beforehand, a memory so vague that you're not sure anymore whether it was a dream or something that actually happened.
Though bittersweet, rediscovering this song after 25+ years was special in its way. Almost as though Jim Henson and songwriter Jeff Moss had put together a time capsule for the express purpose of sending me a posthumous gift. I don't mean to sound self-centered or delusional, but somehow it just feels really personal to me.
