Heads up, I created that chart based on a published score. Comparing it to the music performed by Richie Valens (see YouTube: https://www.youtube.com/watch?v=BycLmWI97Nc ), the score was inaccurate. I'm dropping this song from a setlist since no one in the group speaks Spanish. Makes it tough to correctly chart the song sections -- especially since every bar consists of C, F, and G7! Anyway, this is a starting point if someone wants to polish the arrangement.
