Sunil Grover on Wednesday retweeted an old video from Kapil Sharma's 'Comedy Nights with Kapil' wherein he can be seen performing on song 'Gerua' from Shah Rukh Khan's 'Dilwale'. "Somehow this makes me emotional whenever I see it," he wrote. In 2017, Sunil had left 'The Kapil Sharma Show' following a fight between them, which took place on a flight.
