"If I Knew Then" by Lady Antebellum with lyrics

The first time that I saw youLooking like you didWe were young, we were restlessJust two clueless kidsBut if I knew then what I know nowId fall in loveOn a bus in ChicagoThree rows to the leftYou know my heart was racing for youBut we never even metBut if I knew then what I know nowId fall in loveChorusCause love only comes once in awhileKnocks on your door and throws you a smileAnd takes every breath, leaves every scarSpeaks to your soul and sings to your heartAnd if I knew then what I know nowId fall in loveOn a summer night in AugustIn the back seat of my carInstead of trying to get to know youI took it way too farBut if I knew then what I know nowId fall in loveRepeat ChorusOh I used up a lot of chancesI cant get them backBut if again it comes callingIm gonna make it lastRepeat ChorusOh if I knew then what I know nowId fall in love
