[Verse 1]
E                                  F#m                           A
I got these beliefs that I think you wanna break
E                                        F#m                                                     A
Got something here to lose that I think you wanna take from me
E                           F#m                           A
You say that I\’m asleep but I wanna be awake
E                                                     F#m                                        A
Got something here to lose that I know you wanna take

[Pre-Chorus]
E                                                     F#m
And he said age is just a number, just like any other
A
We can do whatever, do whatever you want
E
Boy becomes a man now
F#m
Can\’t tell a man to slow down
A
He\’ll just do whatever, do whatever he wants

[Chorus]
E                                                     F#m
I went out looking for love when I was seventeen
A
Maybe a little too young, but it was real to me
E                                                                  F#m
And in the heat of the night, saw things I\’d never seen
A                                        E
Oh oh oh oh oh oh, seventeen

[Verse 2]
F#m                                                     A
You should know I\’m green but I\’ll find my way around
E                                                     F#m                                        A
Heard the whispers, now let\’s see what all the talk\’s about
E                                        F#m                                        A
I\’m taking in the sights and measuring the sounds
E                                                     F#m                                        A
Heard the whispers, now let\’s see what all the talk\’s about
[Pre-Chorus]
E                                                                  F#m

E
Boy becomes a man now
F#m
Can\’t tell a man to slow down
A
He\’ll just do whatever, do whatever he wants
