According to the organisers, the event was attended by more than 1,25,000 people to break the record. However, the final decision would be made by a four-member team of Guiness Book of World Record.
Pakistan has recently created a world record in this regard when about 42,000 people sang its national anthem in chorus.
Rohit Kohli, a social worker and one of the organiser, claimed," more than 1,25,000 people sang 'Jan Gan Man' together to set a new world record".
Kolhi said the team of GWR recorded the whole proceedings of the event and it would announce the result soon after going through all the facts and statistics.
School students from around 400 schools in the city participated in the event which also saw the presence of people from various walks of life.
