I have been searching for a specific piece of music off and on for the past four years. The best way I had to describe it was "that one song that was always used for conveyor belt or assembly line machinery in the old Looney Tunes cartoons." You know that one. Then I'd start singing it.

I'd either get confused looks from people or a response like, "Oh, yeah. I remember that. No idea what it's called." Yeah, thanks for nothing.

I'm happy to report that I finally tracked it down. The song is "Powerhouse" by Raymond Scott. It's a 1937 instrumental jazz piece that was liberally used by Looney Tunes.

If Rube Goldberg had a theme song, this would be it. I see Rube making scrambled eggs and toast in the morning using pans, chickens, and some sort of bowling ball contraption while a jazz band in the nook plays this song.

Here it is in Bob Clampett's "Baby Bottleneck":
