Back in the 80s when I was at school Feargal Sharkey sang about a 'Good Heart', which, as a bunch of teenagers, we changed to a 'Good Fart', with (our version of) the chorus being ...
And a good fart
These days, is hard to hide
A good faaaaart, the lasting kind
A good fart
These days, is hard to hide
So please be gentle with this nose of mine
Yes, we were a bunch of typical teenagers but even now almost 40yrs later, if I hear this song on the radio when I'm in my case, I just can't help singing our 'fart' version ?
