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 racing for you But we'd 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 to your soul And sings through 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 If I knew then What I know now Whoa If I knew then What I know now I'd fall in love
