Post the success of 'Edhu Varaiyo', the first single from Nayanthara's Coco, the makers have announced the release date of the second single.
 

This new song will be called Kalyana Vayasu and will release on May 17. Anirudh, music composer of this film, made this announcement with his tweet, "#KalyaanaVayasu - second single from #KolamaavuKokila releases on 17th May 🥁 First-time lyricist 😁 Any guesses?"
 

This song is penned by a first time lyricist and it seems like to be a surprising choice.
