I used to go to 'The Traddie' and the Old crown in 1978-80. There was a duo that went to the traddie who I think sang Radcliffe Highway. The girl's name was Elaine - not sure of the guy's name. There was also a lady called Kay who was a regular that I've seen in recent times at Whitby festival (though not for a couple of years - but that's because of my absence, not hers).
Whoever is being charged with conveying messages to the Black Diamond crowd could they please pass on 'hello' from me to Phil & Derek as well. Too many years since I've been there.
