I also named my Subaru Outback "Claire" in honor of the Gilbert O'Sullivan song.
O'Sullivan also performed one of my favorite Christmas songs called "The Christmas Song."
And no, this is not the "Christmas Song" many might first think of.
Amazingly, with the exception of "Claire", his songs aren't autobiographical for the most part. He just possesses that storyteller's gift of getting inside the heads of the characters he creates.
