[Verse 1: Chris Janson]
I changed the number on my phone
My heart finally found a home
You can't be twenty-one forever
I put the bottle on the shelf
Thought about more than just myself
You can't be twenty-one forever

[Chorus: Chris Janson]
There's a time for young and dumb
For lovers, lines, and songs
You go to bed in the morning
After you stumble in at dawn
Had to get my act together
Learn to appreciate stormy weather
You can't be twenty-one forever

[Verse 2: Dolly Parton]
The cards aren't always jacks and aces
Pretty soon you gotta face it
You can't be twenty-one forever
Write your story, but turn the page
Don't be afraid to act your age
Woah, you can't be twenty-one forever

[Chorus: Chris Janson and Dolly Parton]
There's a time for young and dumb
For lovers, lines, and songs
You go to bed in the morning
After you stumble in at dawn
Had to get my act together
Learn to appreciate stormy weather
You can't be twenty-one forever
[Post-Chorus: Dolly Parton]
Oh, oh-oh, oh

[Bridge: Chris Janson, Dolly Parton, Chris Janson and Dolly Parton]
So enjoy it while you can (Enjoy it while you can)
'Cause it's just a number, man
Like wine, you only get better all the time (All the time)
And there's a beauty with growing up
So pour it out, and fill the cup
'Cause you can't be twenty-one forever (Forever)
No, you can't be twenty-one forever (Forever, forever)
Ooh (Ooh)

[Outro: Chorus]
Twenty-one forever
Twenty-one forever
Twenty-one forever
Twenty-one forever
Twenty-one forever
Twenty-one forever
