Not a comic recitation

Back in the 1950s. on a regular program broadcast in the early afternoon on Radio Eirian, the host, a chap called Dinjo, recited a poem about the aunction sale of a fiddle.

The aunctioneer was having a hard time with no bids forthcoming when from the back of the hall cam an auld gaun bodie [a tramp]. He took up the fiddle and with his playing, reduced the audience to tears.

Anyone have the words for this.
