The Norris Brothers

My chief mechanic constantly crows
His brother the MD surely knows
They have nomenclature of similar prose
A younger brother and a love that shows
Some love just grows and grows
For the Norris Boys will never be foes
No chance they could come to blows
A love of each other a surname chose
Two good men in different clothes
One looks after buses parked in rows
Another helps managers avoid their lows
Eclectic brothers and boy it shows
One barracks for the Tiger’s, football Pro’s
The others a Magpie with a face that glows
