I seem to be the only reader whose head this didn't go over. Just been catching up with January's progs and immediately recognised very thinly disguised versions of our erstwhile boarder (and my friend and former neighbour) Johnny Stress with his twin brother Danny. Johnny has the rockabilly 'do while Danny has the mutton chops. Unconvinced? One of the real brothers has, or had, a pet spaniel. Still unconvinced? Mike Carroll didn't even bother to change their surname!
PS I told Johnny today; he read through his latest progs and was suitably chuffed.
PPS I know you're still lurking here, McMonagle - hope you don't mind me posting this

PPPS They're both way slimmer and handsomer than Tiernan Trevallion has them.
