I think this is from the '50s (or the '40s, or the '60s), the sort of thing Leroy Anderson may have written. Instrumental, played very fast, straight eighth notes, by pizzicato strings. I think it was the theme song for a radio or tv show, and may also have been used in cartoons.
Something like this:

The damn thing has been stuck in my head for three days now.
It’s definitely Holiday for Strings, composed by David Rose. I can’t find any “straight” recordings online, but here’s a video featuring a typically wacky version by Spike Jones and His City Slickers. Composers such as Alf Clausen and Laurie Johnson have also written some cues for television meant to mimic the same style (Clausen’s for The Simpsons, Johnson’s for a British production music library).
