Se me olvidaron las palabras

I was going to tell you how much fun I had yesterday and how tired I am today, but I forgot the words, I forgot the words. Then this song came to my mind and I played it there until I forgot the words, I forgot the words. But the melody lingers and it'd stay with me all night. I am so sorry, I didn't mean to forget, but I did, I forgot the words. Daddy's birthday is on Monday, I'll call and sing a happy birthday, and say I love him from afar and that I forgot how old he is.
