Russ Johnson of Canon City, Colo., noticed something familiar between Nelson Riddle’s “Route 66” theme for the original 1960s television show and Danny Elfman’s main theme for “The Simpsons.”
So he created a mashup of the two. It’s a bit disorienting at times, but it does contain a few striking similarities in its melody and arrangement:
To compare the two, I’m posting both musical themes separately. First, “Route 66.”

Then, “The Simpsons.”
