I seem to recall a music hall piece I only have a snatch of it from a tape off the Radio many years back, with no details - it got taped over.
The subject appears to be road racing, the bit I recall runs:

Up the road,
away went Polly
with a step so jolly
That we knew she'd win
Off she went,
The pace was killin'
But the mare was willin'
For a lighting spin.

All the other 'orses there
was like they've ne'er been born
"Whoa there, whoa mare!
You've earned your little bit o'corn"

Anyone know it (or know of it)?
