Changing Tunes

I used to not mind breaking hearts
And ending things before they'd start
I used to not mind torn apart
Yeah, I used to not mind breaking hearts

I used to not mind party nights
The last to leave, the first to fight
I used to not mind being right
Yeah, I used to think I was always right

Ah, but then I met your mamma
And when I held her hand
And I-I-I knew that God had a different plan
That I give up the long nights of howling at the moon
'Cause she taught me to change my tune

I used to not mind miniskirts
I used to not mind see-through shirts
I used to not mind girls that flirt
Yeah, I used to not mind miniskirts

Ah, but then I met you daughter
And held you by the hand
And I-I-I knew that God had a different plan
And I'd give up the long nights of howling at the moon
'Cause you taught me to change my tune

I used to not mind growing old
I used to not mind tomorrow
But when we both turn grey and old
You'll still have a hand to hold

Yes and when I meet him daughter
I'll shake his sweating hand
And I-I-I know that he'll be a gentle man
'Cause I know how we raised you
And I swear I'll play it cool
When I tell him all the ways you'll change his tune
