The Killigans
playing Santi Anno at Duffy's Tavern. I like
this version even better. Same song, same band, and still like a punk song should be.
A gazillion other versions, many of them good, can be found on YouTube.
Be warned, the melody is an addictive masterpiece. You'll never get it out of your head again.
So why would anyone write a song about the Mexican general who won the Battle at the Alamo (Santa Anna) in the shanty genre? The lyrics here are no longer connected, but the original was.
