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 going 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 ´caus? I used to be young Take on?, pour it out It´s not worth cryin´ about 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, ooh 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 Oooh Oooh Ooh ooh ooh Yeah Oooh Oooh Ooh ooh ooh 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
