The rest of the writing on the back of the photo seems to be in some Asian language, my guess is these guys are Indonesian or Filipino, surf music was huge in the south Pacific. If you want to see the greatest Indonesian band ever see the Nov. 19th, 2008 posting on the Tielman Brothers. Then again this could be Mexico, or anyplace south of the border. The writing could be some sort of Aztec or Mayan hieroglyphics. There were some amazing Mexican surf and garage bands-- Los Locos Del Ritmo being the best that I've heard. Here's their version of Pedro Pistolas (Peter Gunn), played in Spanish. Getting back to these rockin' greaseballs, they seem to be standing outside a village, and I bet those guitars came from a factory somewhere nearby, they look brand new. They must have fallen off a donkey.
BTW: Check out Miriam Linna's (A-Bones/Norton Records/Kicks & Bad Seed mag) new blog: Kicksville 66. First entry is her amazing memoirs of her first year in New York City as the original drummer in the Cramps.
