Speculation by PAT in characteristic manner on the origins of the ‘Humpty Dumpty’ and ‘Sing a Song of Sixpence’ nursery rhymes leads him to consideration of composers being unconsciously influenced by half-remembered tunes – their own or others’ – in a process of ‘seepage’. Very much in the style of similar articles written for the Cambridge Review in the 1950s, and covering in part the same ground as ‘The Truth About Tunes’ published there on 4 June 1955, this is the sole example of the genre to be published in the Caian and perhaps the last that he wrote.
