Bernard Miles used to do this when he did his 'leaning on a gate' monologues, which always ended with 'I'm gooin'ter sing te thee now'

Where be that blackbird?
I know where 'e be,
'e knows I, I knows 'e,
'e knows I be arter 'e,
Where be that Blackbird?
Round yon wurzel tree!
Good arternoon!

Another one he did was:-

Four seeds in an 'ole,
One for the rook and one for the crow,
One ter rot an' one ter grow,
Good Arternoon!

I wish I could remember all the monologues, there was a particularly good one about the effigy of a crusader in the local church with a grapic description of the statue with his dog at his feet, ending with the remark 'I reckon as 'ow 'e's the best bit o' sharpenin' stone in Hertferdshire'.
It goes on ' An 'is ol' missus is there aside him as well. 'er's no good tho, can't get any edge out on 'er at all!'

Lovely stuff!
