IN RESPONSE to Mrs Clare's letter of June 28, I am appealing to those who like her, and myself, have good reason to be grateful both to the ambulance service and to the Cardiac Unit at Derriford, to support a concert to be held at Trethorne, Launceston with Johnny Cowling, entertainer and comedian, on Friday, September 11.

This is to raise money for the Plymouth based charity Heartswell South West, which is at present aiming to raise £120,000 to buy a new, non-invasive diagnostic instrument, which will have a tremendous impact on cardiac care.

We all know this to be a fine unit and worthy of our support.

For further information and offers of help, please contact me on 01566 772882.
