This is a different way to play this song, the other chords uploaded are completely correct, but if you don't wish to down-tune, here is a way you can avoid it. Capo 4 [Intro] D [Verse 1] D G D My Grandpa gave a wheat penny and I kept it in my pocket D A I had big plans in my back yard to build me a space rocket D G D I talked to my brother on a fake CB that I made from a tic-tac box D A D I packed my snowballs nice and tight but in the middle I put rocks [Chorus] G D Don't trade in your tic-tac box for a ball on the end of a chain A And don't go spending Grandpa's pennies buying into the game G D You gotta keep your heart young A Bm Don't go growing old before your time has come G D You can't take back what you have done A D You've gotta keep your heart young [Verse 2] D G D Dad took the wheels off of my bike and he pushed me down a hill A But speed got the best of me and I took my first thrill D G D That was back when alcohol was only used on cuts A D It stung like hell so I jerked my leg and momma said it'd give me guts [Chorus] G D Don't trade in your tic-tac box for a ball on the end of a chain A And don't go spending Grandpa's pennies buying into the game G D You gotta keep your heart young A Bm Don't go growing old before your time has come G D You can't take back what you have done A D You've gotta keep your heart young [Verse 3] G D So take a picture of the one you love and put it in a locket A Go dig up your time capsule and the blue prints for your rocket D G D Keep in touch on a fake CB, that same old tic-tac box A D Pack your snowballs a little less tight but in the middle still put rocks [Bridge] G D And keep your heart young A Bm Don't go growing old before your time has come G D You can't take back what you have done A D You've gotta keep your heart young [Chorus] G D You gotta keep your heart young A Sometimes you don't die quick Bm Just like you wished you'd done G D The love is a loaded gun A D You've gotta keep your heart young G D Bm You can't take back what you have done is done A D You've gotta keep your heart young
