If you’re a musician, sometimes you get weird gigs.  Sometimes something goes terribly wrong and it can ruin your show.  If you’re this band, however, you turn lemons into lemonade.  At the Plaza Patria Mall in Guadalajara, a bad roof leak caused the first floor to start flooding.  The band playing the mall at the time seized the opportunity and broke out into a cover of “My Heart Will Go On,” the Celine Dion juggernaut of a song from Titanic.
