Thanks for the replies - sorry it's taken so long to get back! The tune is definitely very similar to the one given in the Mudcat link at the top of the page (under Nightingale). It's close enough to have brought some great memeories back when I played it! But the lyrics you suggest are not as I remember. The end line of the chorus was definitely something about the nightingales as 'they sang in the valley belooooow' - that last bit is the drawn out warble I refered to. Probably not making much sense! I will be visiting the area in a few weeks. I intend to find what exactly the words sung locally are and, if anyone is interested I can post them here.
