Sound system fails at Kejriwal's Delhi Dialogue

For the second consecutive time, sound system failed as AAP chief Arvind Kejriwal stepped onto the stage to make a speech during his Delhi Dialogue.
Usually, the sound system operator is asked to play the popular Vishal Dadlani-composed song 'Paanch Saal Kejriwal' before the leader takes the stage.
Ironically, the system worked perfectly fine for almost one and half hours before he came onstage.
The moment the AAP chief, clad in red sweater, cream trouser and trademark muffler, stepped onto the stage, the system went off due to some loose connection, for a couple of minutes.
A similar incident happened during the last Delhi's Village Dialogue held in Matiala when Kejriwal stepped onto the stage. The problem was solved in a couple of minutes then too.
