He loved the song, Girl, by Davy Jones. He'd bark and dance around the room, whenever it played. It finally dawned on me, that with Davy's accent, Gurl sounded a bit like Gull. So that became his theme song. I sang a bit of it to him, before I had to put him to sleep. I'm sure he's dancing along with it, somewhere up there in Heaven now.
Love ya, Gull!
