"Yeh Dooriyan... was the first song that was finalised for this film, and I wanted Mohit Chauhan to sing this for Love Aaj Kal. It took us more than a month to hunt down the singer, " stated Pritam in an interview.
Mohit is from Delhi and had sung in Imtiaz's first flick Jab We Met. "Imtiaz caught hold of Mohit's friend and requested him to get Mohit's phone number from his home-town in Delhi. Finally after the tiring hard work of almost two months, Imtiaz and I were able to reach Mohit for Dooriyan, " he adds further.
"This is one of my favorite songs from the film, and Mohit has really done well with his pitch as a singer. Imtiaz was very strict and wanted voice of the lead singers than just the music, making it simple and elegant. Today this song is liked by many and we are very happy about the same, " he concludes.
So finally the dooriyan was erased with Mohit agreeing to sing the song.
