Third time lucky!!!!
Harvesters???? should note that heat was a typo - my apologies - too much of a dinosaur to handle such eleborate machinery. You are correct in assuming that this should have been heart. My apologies also for the layout & lack of abbreviation - I was not aware that the computer would re-hash my imput. Being a newcomer to this site - it makes me wonder how the next generation of the aural/oral tradition will pass on our heritage of song with the possibilities of typos etc - a classic example appears to be the word "curties" in the lyrics posted of The Carter.
