Oh, I built so many temporary bridges
That would only hold your love for just a day
I can see there's nothin' I can do to hold you
But there's one thing you can never take away

And you'll go down as my greatest memory
Today's the day I always prayed I'd never live to see
Oh you built me then tore me down and now you're leavin' me
But you'll go down as my greatest memory
[ Lyrics from: http://www.lyricsfreak.com/m/marty+robbins/my+greatest+memory_20267463.html ]
Oh, I hope you find someone to paint your rainbow
And all the dreams you pictured in your mind
Oh, I still don't know the reason why you're leavin'
But every trace of you that's left behind

Will go down as my greatest memory
Today's the day I always prayed I'd never live to see
Oh you built me up then tore me down and now you're leavin' me
But you'll go down as my greatest memory
Yes you'll go down as my greatest memory
