Open Culture:

Ray Ellis had a six-decade career as a producer, arranger, and jazz composer. And while he’s best known for arranging music for Billie Holiday’s Lady in Satin (1958), he also enjoyed a long career orchestrating music for television. Working under a pseudonym “Yvette Blais” (his wife’s name), Ellis composed background music for the cartoon studio Filmation between 1968 and 1982. And, during the late 60s, he notably created the background and incidental music for the original Spider-Man cartoons.

If you watch/listen to this, I guarantee you’ll be singing the theme song for the rest of the day.
