It looks good on paper, Pink & Sia. REAL singers. But the actual result is disappointing. The chorus is... well non existent. They don't sing together, it's just alternating between one another. That's not what I call a duet, what a waste, they could have done something epic. Not the right song and certainly not the right choices and production. IMO the last big duet between 2 females that was released is "When You Believe".
