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
