"Count On Me"
Sung by Bruno Mars

[Verse 1:]
Oh uh-huh
If you ever find yourself stuck in the middle of the sea
I'll sail the world to find you
If you ever find yourself lost in the dark and you can't see
I'll be the light to guide you

We find out what we're made of
When we are called to help our friends in need

[Chorus:]
You can count on me like 1, 2, 3
I'll be there
And I know when I need it
I can count on you like 4, 3, 2
And you'll be there
'Cause that's what friends are supposed to do, oh yeah
Ooooooh, oooohhh yeah, yeah
