I am looking for a version of this music video (see below) for The Carpenters' "Top of the World", but Richard Carpenter is way older. It begins with a monologue by Richard, in the background of which a stand-in for Karen dances, while he opens with, "Some magical things happen at Christmas, and we have one such thing for you tonight." (non-verbatim) He then discusses that the song was written in 1972, became a hit in 1973, and then again in 1995 when it was featured in Miseinen (a Japanese drama). Then, he approaches the piano and the music video plays with footage of Karen from the video below, but with Richard being much older.
It was on YT years ago but has disappeared. No idea what the title was, or who made it.
