 The auditions were successful, and the La Bambas appeared on stage for the first time on May 25, 1966 at the Coconut Grove inside Galle Face Hotel.It didn't go as well as they wished, however, as they were booed and jeered off the stage.This was just a minor setback, and the La Bambas recovered to become one of the most popular Sinhala bands of the 1960s.
