Through both work and personal preference I've seen a lot of Bollywood in my time. Combining dance AND a capella singing? Coming from someone who can barely chew gum and walk at the same time, that's just pro.
Let's admit it, watching a couple sway back and forth for three and a half minutes isn't the most riveting thing, especially after sitting and watching them stand and gaze at each other for anywhere from ten to sixty minutes beforehand.
