Ford was humming something. It was just one note repeated at intervals. He was hoping that somebody would ask him what he was humming, but nobody did. If anybody had asked him he would have said he was humming the first line of a Noël Coward song called “Mad About the Boy” over and over again. It would then have been pointed out to him that he was only singing one note, to which he would have replied that for reasons that he hoped would be apparent, he was omitting the “about the boy” bit. He was annoyed that nobody asked.
