2. I love you, and the song that I sing is the only way that I can explain

That's a Cat Stevens song as well. I know the whole song, but for the life of me I can't recall the name. The chorus keeps having lines starting with "I love you"... moutains to sand... old man... etc. It's one of my favorite Cat Stevens song. Dammit, what is the name? This is really going to frustrate me, not being able to remember....
