Menolly's hymn is called "The Good Old Way" and is a primitive Methodist hymn.
My Dad reckons he heard it sung in the chapels round our native village and always thought of it as an Isle of Wight hymn. Others reckon it came originally from the Isle of Man.
Either way it's a cracker and I love it as a chorus singer and a as a lead singer. It was really hard going to learn, the phrasing is critical if you want it to sound good.
