Not exactly "Mexican Hat Dance", but I strongly recommend 2 cds by Dr Loco's Rockin' Jalpeno Band, MOVIMENTO MUSIC for political songs (including Spanglish versions of "Study War No More" and "We Shall Overcome"), and PURO PARTY for more social stuff ("Esperanza", "Rosamaria", and even "Wooly Bully"). Both are on Flying Fish and available through CDnow or preferably from Dr Loco himself at www.drloco.com. (Sorry, I'm very new at this and dont know how to set this up as a link. But check the site out anyway.) "Esperanza" is one of the best songs I've ever heard.
