The first album I ever owned was by a group called The Collectors (whose later incarnation under the name Chilliwack was a bit better known). I can't remember how I came to own this record album - it seems to me that somebody was moving house and gave it to me. The second album I owned was a little more sophisticated - Herman's Hermits.

Anyway - back to The Collectors - there's this girl called Lydia who wears purple and lives in a steeple. The most pressing thing for the songwriter(s) would appear to be to have words at the end of each line that rhyme. Little else matters.
