I’m in the process of inventing a new musical instrument. It’s called ‘The Comb-O-phone’ It’s still at the prototype stage as yet, things will resume when my test musician (Hampton) Is released from Withington Facial Trauma Ward 4. I don’t want to infringe my own copyright so all I can tell you is once I considerately reduce the voltage to the tin foil around the comb (and Hampton’s new lips have taken)...you could next see me on Dragon’s Den.
