Carl's Jr.'s new commercial features a stunning, mermaid-like blonde model seductively crunching into a charbroiled Atlantic cod fish sandwich while walking on the ocean. In the background plays a light-hearted, lounge-y song about the sea. Hmmm, the tune kind of sounds familiar. What is it?

The song is 'Beyond the Sea' by Bobby Darin, but it's actually a cover of a French tune originally from the '30s. That said, Darin's 1958 version is the most recognizable, garnering the crooner world fame and becoming one of his biggest hits.

In addition to the Carl's Jr. commercial, Darin's 'Beyond the Sea' has been featured in countless TV shows and films, including 'Finding Nemo, 'Apollo 13,' 'Austin Powers in Goldmember' and 'Goodfellas,' just to name a few.
