There's a generous 2-minute sound sample at CD Baby:

BREAKING WIND SUDDENLY
Words, Les Barker. Tune, BLOW THE WIND SOUTHERLY.

Breaking wind suddenly, suddenly, suddenly
Tends to exclude one from society.
Breaking wind suddenly, suddenly, suddenly,
I blamed the dog but they knew it was me.
A friend said to me there were jobs in the offing,
So I hurried to town as an interviewee.
I was almost employed when my hopes were destroyed
By a thund'rous eruption. They knew it was me.

Breaking wind suddenly, suddenly, suddenly
Somehow I feel did not help my cause.
Breaking wind suddenly, suddenly, suddenly,
I spelled out fart with impeccable noise Morse.
I knew they were pleased with answers I'd given,
And all were [impressed?]....

[As sung by Alison Younger on "Tubular Dogs," Mrs Ackroyd Records, DOG 014, 1999.]
