Released in August 2002.
It’s a song that sings the American folk tune also known as “My Grandfather’s Clock,” with a beautiful, soothing vocal that’s perfect as a lullaby and feels cleansing to listen to.

It’s a warm number that could be called the essence of Ken Hirai.
Pop starHirai Ken
It’s a slightly high-difficulty song that really tests your vocal ability, but when a skilled singer performs it, you’ll go “whoa!” (Conversely, if it’s sung poorly, it can really kill the mood, so it’s truly for advanced singers.) The accompaniment is quiet, so how about placing it around the middle when people are getting tired of loud sounds?
