Jim Henson and Raymond Scott's "Wheels That Go" (1967)

"Wheels That Go," a gorgeous 1967 short film by Jim Henson, starring his son Brian, with music by pioneering jazz and electronic music composer Raymond Scott. You'd recognize Scott's big band music from hundreds of Looney Tunes and Merrie Melodies cartoons. Many of those familiar tunes are available on the compilation Reckless Nights & Turkish Twilights. Scott's experimental electronic pieces, like the one in this film, can be heard on the collections Manhattan Research Inc. and the Soothing Sounds For Baby series.
