Am I the only one to make the connection Quantity Surveyor/Richard Stilgoe?
RS wrote a folk song parody which went (from memory) something like this :-

A Quantity surveyor in a public bar did sit,
He wore an Arran sweater, a great big chunky (k)nit,
He supped a nervous pint of ale because he knew e'er long,
He had to sing the Folk Club in the public bar a song!

Hi me roo collapsum roarem,
Hi me roo fa lay oh,
Fol dol riddle diddle, diddle iddle I doh,
Diddlin all the day oh!

Just then two more Surveyors came walking in the bar,
One pulled a banjo from a case, the other a guitar,
They sang a brisk sea shanty, each Arran sweatered man,
As only three town dwelling Quantity Surveyors can!

Hi me roo collapsum roarem,
Hi me roo fa lay oh,
Fol dol Riddle diddle, sea sick in a row boat,
Keep the waves away oh.

That night they made a solemn vow to go full time a-playing,
To travel round the folk clubs and go no more surveying,
They played a score of choruses, they drank too many beers,
And they sang in funny voices with their hands behind their ears!

Hi me roo collapsum roarem,
Hi me roo fa lay oh,
Fol dol riddle diddle nine pints tiddly,
Real ale rules OK oh

The moral of this little song, if moral there be any,
Is men who go folk-singing always sing one verse too many,
The reason is, we're all afraid that someone might betray us,
And make us all go back to being Quantity Surveyors!

Hi me roo collapsum roarem,
Hi me roo fa lay oh,
Fol dol riddle diddle, Fothergill and Harvey,
Quantity Survey-OH!

I did sing it once, people threw things at me!
