Classic rock songs would replace the traditional bell in a school in the Bulgarian Black Sea town of Kavarna in the school year 2013/2014, its Mayor Tsonko Tsonev said Monday. In September, the month of AC/DC, the classes in the secondary school \"Stefan Karadzha\" would begin with Touch Too Much, and end with Thunderstruck, Tsonev said at the opening of the school year. October would be the month of Ronnie James Dio, followed by Billy Idol, Whitesnake and some popular Bulgarian rock bands, Tsonev added. Kavarna is popular as the \"Rock capital\" of the Balkans. Over 40 world celebrities such as Manowar, Deep Purple, Scorpions, Whitesnake, Dio, Accept, Nazareth, Saxon, Billy Idol and Twisted Sister have performed in recent years in the town.
