Okay this is driving me crazy , there is a song called nah nah or so I think and they actually play it on the nacho libre trailer, I don't think its on the soundtrak though. It has a guitar in the background and its real distorted, the words I caught are just, na na nananana na na na , yea not much of a clue but I am dying to figure it out. Please answer back. Thanks

This may be a wild stab in the dark (and I haven't heard the Nacho Libre trailer), but I'm wondering if maybe this is an older song (from the 80's) by the band "Journey"? They had a song that had that "line" in it and I believe it was called "Lights". It's about San Francisco and has a line in it that says, "When the lights go down in the city, and the sun shines on the Bay"... I may be waaaaay off, but this is what it sounds like to me! Good Luck! : )
