"Hey Brother" is song by Swedish producer Avicii from his debut studio album, True (2013).

Hey brother
There's an endless road to rediscover
Hey sister
Know the water's sweet but blood is thicker
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do

Hey brother
Do you still believe in one another?
Hey sister
Do you still believe in love, I wonder?
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do

What if I'm far from home?
Oh brother I will hear you call
What if I loose it all?
Oh sister I will help you back home
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do

Hey brother
There's an endless road to rediscover
Hey sister
Do you still believe in love, I wonder?
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do

What if I'm far from home?
Oh brother I will hear you call
What if I loose it all?
Oh sister I will help you back home
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do
