Sisters Wendy and Nicola had always wanted to find out more about their mysterious maternal grandmother, so they hired a genealogist to explore their family history. Research revealed that Wendy and Nicola's grandmother was a music hall star in the 1920s - and not only this, the sisters also discovered a cousin, Helen, who they never knew existed. All three cousins get together for the first time and head to Covent Garden to discover more about their family's fascinating musical heritage. The programme also meets Allan Skeggs, who carried out his genealogical detective work himself. Years of searching finally led him to his half-brother David. David discovers more about the father he never knew, and Allan gets to see to the children's home where David grew up, before sampling his newly discovered older brother's favourite pie and mash shop in the East End.
