"There are, of course, many ways to insult your fellow man. You can claim a chap’s mother keeps a slatternly house. You might infer his sister is missing a certain aesthetic loveliness. Or even – lawks! - that he himself, is unlikely to stray from life’s Dunce Corner. The Phenomenal Handclap Band, however, have chosen to impugn the earning capacity of 15 to 20’s lyrical nemesis, and they are either saying that he/she does not earn as much as he/she claims, or that he/she is a cheapskate – all because they use public transport. And – oh, goodness me - what a lovely little insult this pop song is"
