Join us for a programme of musical performances, talks, craft activities and workshops based on the 17th century Broadside Ballads from Bodleian Library, with the award-winning 100 Ballads project team. Broadside ballads were the pop music of the 17th century, selling in their thousands for a penny a piece in the market place. Their subjects were love, politics, battles, crime, folk tales, and sensational accounts of monsters and disasters. The ballads were sung to the hit tunes of the day, and many of them survived as folk songs into the 20th century.
