Yondu Whistling over Drifter Ult

So I was recently re-watching guardians of the galaxy and the second I saw the scene with Yondu I knew what I had to do. 

Note: The whistling during Drifter's ult only plays if the enemy Drifter ults, not if he's on your team (or if you're playing him). This is intended behavior, not a mod issue!
