The truth is bulletproof there`s no foolin` you I don`t dress the same Me and who you say I was yesterday Have gone our separate ways Left my livin` fast somewhere in the past `Cause that`s for chasin` cars Turns out open bars lead to broken hearts And goin` way too far I know I used to be crazy I know I used to be fun You say I used to be wild I say I used to be young You tell me time has done changed me That`s fine I`ve had a good run I know I used to be crazy That`s `cause I used to be young Take one pour it out it`s not worth cryin` `bout The things you can`t erase Like tattoos and regrets words I never meant And ones that got away Left my livin` fast somewhere in the past And took another road Turns out crowded rooms empty out as soon There`s somewhere else to go oh oh I know I used to be crazy I know I used to be fun You say I used to be wild I say I used to be young You tell me time has done changed me That`s fine I`ve had a good run I know I used to be crazy That`s `cause I used to be young Oh oh oh oh oh oh oh oh Oh oh oh oh oh oh oh oh Oh woah oh woah oh woah oh Yeah Woah oh oh oh oh oh oh oh Woah oh oh oh oh oh oh oh Oh woah oh woah oh woah oh I know I used to be crazy Messed up but God was it fun I know I used to be wild That`s `cause I used to be young Those wasted nights are not wasted I remember every one I know I used to be crazy That`s `cause I used to be young You tell me time has done changed me That`s fine I`ve had a good run I know I used to be crazy That`s `cause I used to be young
