Gillian Reynolds is the distinguished radio critic for the Sunday Times. She has chosen Folk Map as the Pick of the Day for the last two Saturdays, calling it a landmark series and a prime example of public service radio. And this week she has written a glowing review; "Here's a programme made from the heart, about the power of music to lift people of any age, any country, any social rank, above drudge and grudge....No commercial station will ever offer radio like this." I don't know if she is a late convert to folk music - her varied selection for Desert Island Discs didn't include any. But she is valuable ally.
