I'm a resident of Hazel Grove (formerly Bullock Smithy) and have a home recording of the 'Ballads of the North West' programme about lead mining. This programme featured Bullock Smithy of whom I have some recollections seeing them performing at Poynton Folk Club.
If you e-mail me Pete (you will need to sign up to Mudcat) I'll try to find the recording and get a copy to you.
