Long John Silver's Ad

[The MightyMeatSauce]

Does anyone know the song from the Long John Silver's Ads? It's basicly a guitar playing a simple riff, followed by some vocals (sounds like "Yea yea"). The song gets stuck in my head whenever I see the commercial, but no one has posted anything anywhere about it. And then I went to a water park last week and the friggin' intercom played the song. No one working there knew where the sound system music came from, so I'm still searching...

Thanks in advance for the help and the site!
