Foolproof are Sue Hudson (vocals and guitar) and Cliff Baylis, (vocals mandolin and guitar). Sue, formerly with folk duo Tundra has been performing for over 20 years. Cliff is a skilled and inventive musician, having played mandolin and guitar for many years. Drawing heavily on their shared experience of roots music on both sides of the Atlantic, their sound is a mix of country and folk, with overtones of blues and gospel.

The musical paths of Sue Hudson and Cliff Baylis have crossed frequently over the years and their shared enthusiasm for American music has now led to them forming the duo foolproof, which has appeared in festivals, concerts, folk clubs and pubs across the South of England.
