Famous singer KK passed away in Kolkata on Tuesday night, when he was performing at Nazrul Mancha for Gurudas College's fest. Apart from being one of the top singers in Hindi, KK was a highly sought-after voice in South Indian languages too. 

His combinations with composer Harris Jayaraj have invariably been chartbusters and together they delivered memorable songs like Uyirin Uyirae (Kaakha Kaakha), Kalyaanam Thaan (Saamy) and Andangkaka (Anniyan). Harris' comeback album The Legend, which was released last week, also had two songs Konji Konji and Popopo sung by KK. 

A heart-broken Harris shared on Twitter that he has lost his 'Uyirin Uyir'. He wrote, "My Uyirin Uyire passed away. RIP Singer KK. What a shocking news to hear when the whole world is praising his last song Konji Konji. I am completely shattered and my condolences to his family and friends." 

Condolence messages have been pouring in for KK from all over the country.
