Leveller:Betjeman was from a well-to-do middle class background,foreign to boot.He would probably been regarded as 'trade'with several Establishment counts against him,to which he added a few of his own devising.
Does the young man struggling with his bow-tie and noticing the 'unmade',i.e. private,roads sound at ease with the'upper classes'?
