Gaurav and Kartik Dev, who make their Bollywood debut with the upcoming Akshay Kumar-starrer, 'Bellbottom', say the track 'Marjaavaan' had been in their kitty for a while. “Working with Akshay sir has been a dream, and with this romantic track, penned beautifully by Gurnazar and rendered by Asees Kaur, we’ve been able to create a piece we are truly proud of. We were working with Gurnazar on another project, and one of the songs created [as an option] was this one. It had stayed with us. Akshay sir loved it and it proved to be an ideal project for us to launch with,” says Kartik of the recently released song.
