As part of the Music and Dementia at the BBC project, Eric Knowles revisits antiques that remind us of good times and looks at how antiques and music can help those living with memory loss and dementia. The Milestones museum in Basingstoke plays host to this special show, and Eric also pays a visit to the Music Memory Box project in Bristol. Eric drops in on some of our favourite experts and auctioneers and shares hints and tips on buying or selling music-related items from the past.
