Speakers till 10 ..Earphones after then ! -Midday
This happens only in Mumbai. Members of the Naidu Club Navratri Mandal in Kora Kendra, Borivli, have found a unique way to play garba till the next morning, without violating the Supreme Court order of the 10 pm loudspeaker deadline. All the dancers will be given wireless earphones and the music will be relayed through a radio frequency.

Says the mandal’s chairman Ganesh Naidu, "Recorded music will be relayed through a transmitter in the earphones. We are going to use radio frequency for which we have got a license. We are also getting permission from the Telecom Department. People will have to pay a deposit for the earphones, which they have to return when they leave".
