First of all... social media, quite frankly, is the toilet of the internet and what it's done to pop culture is abysmal, people saw love and, guess what, that's what we wanted to you to see. This is a love song.
From a performance perspective, it was so important to both of us that we were connected the entire time, i've had my arms wrapped around Tony Bennett for three years touring the world. When you're singing love songs, that's how you want people to feel.
