Quote GUEST: question--"Does anyone know the song that Esteban is playing at the end of the geico commercial?"

No, but you'll notice it ain't one of HIS POS guitars he's playing! If you ever need a laff, go to a place called "Harmony Central" (dot com I think) and read reviews on the Esteban "hand-made" gits. I'll bet you wont see the Gecko playing one either. Someone actually threw his guitar into a tree after bashing it up pretty good and it became a bird house. LOL.
