作词 : Williams I sat down to say it The words wouldn't come I just couldn't play it You tore me all apart The bell I tried to ring it The words wouldn't come I just couldn't sing it I used to know this song by heart I used to sing this song to you for days and days In so many different manners, in so many different ways I used to think this dream we shared would never come apart I used to know this song by heart I used to sing this song to you for days and days In so many different manners, in so many different ways I used to think this dream we had would never come apart I used to know this song by heart So when I sat down to say it The words wouldn't come I just couldn't play it, tore me all apart Used to know this song by heart I said I used to know this song by heart Said I used to know this song by heart I used to know, I used to know it I used to know this song by heart
