After you become 18;-), if you live near Oxford, a painless way to introduce your friends to Spiers/Boden and folk music generally might be to take them to the Half Moon in St Clements, Oxford, on a Sunday night. Sessions there are held regularly, with Spiers/Boden as well as the odd Bellowhead member, Ian Giles and Ian Woods presiding. You can take them on the "it's just for a drink" basis, and can leave if they don't like it - it's not formal like a folk club. But you do get some glorious playing and singing. Beware: the sessions run till past 2am, and have been known to finish at daybreak - Boden, Giles and Woods live over the pub, you see.
