Eric, there may be an Irish connection. Shammick is the local name for the village of Combe Martin, but why that should be so remains open to conjecture. Back in the 13th Century and later, Irish people came over to work in the silver mines here, and that may be how the name came into being in the local area.
And Irish music is as welcome at Shammick Acoustic as any other kind - just to get back to the thread!
