As The Chainsmokers sang "Closer", thousands present at their second Indian gig sang along to the worldwide-hit track. Grammy winning DJ duo Andrew Taggart and Alex Pall, also known as the "The Chainsmokers", performed at the Road to ULTRA music festival, here tonight.
Towards the end, they asked the audience to flash the light of their cell phones. Alex got on the podium and waved the Indian flag as the duo played their chartbuster "Don't Let Me Down". The crowd, estimated between 2500-3000, sang along to the track as Alex kept on waving the flag, setting the perfect farewell mood. "It was good to be here Mumbai. We love you a lot. Namastey," the duo said before closing their gig. Their penultimate song, "Honest", was accompanied by fireworks as some fans waved the national flag while others sat on top of someone's shoulder to get a better view of the artistes.
