The first time that I saw you Looking like you did We were young, we were restless Just two clueless kids But if I knew then what I know now I'd fall in love You're on a bus in Chicago Three rows to the left You know my heart is reaching for you But we never even met If I knew then what I know now I'd fall in love 'Cause love only comes Once in a while And knocks on your door And throws you a smile And takes every breath Leaves every scar Speaks through your soul And sings to your heart But if I knew then what I know now I'd fall in love On a summer night in august Backseat of my car Said I'm trying to get to know you I took it way too far But if I knew then what I know now I'd fall in love Whoa, 'cause love only comes Once in a while And knocks on your door And throws you a smile And takes every breath Leaves every scar Speaks through your soul And sings to your heart But if I knew then what I know now I'd fall in love Whoa, I used up a lot of chances But you give them back But if again it comes crawling I'm gonna make it last 'Cause love only comes Once in a while And knocks on your door And throws you a smile It takes every breath Leaves every scar Speaks through your soul And sings to your heart And if I knew then what I know now Whoa, if I knew then what I know now I'd fall in love
