In this episode Mark De-Lisser is in the Welsh Valleys, where the decline of the mining industry has had a real impact on communities, leaving some people feeling less connected. He starts out in Aberdare market, hoping to recruit members for his next choir and show people how singing in groups can make their lives better. He meets Carol, who grew up in the Bahamas and settled in Aberdare 13 years ago with her Welsh husband. Unlike her home town, where there was a strong community feeling, she mainly works from home and finds it lonely. Stay-at-home mum Carys also joins the team, as does ex-solider Carl, who left the army to care for his disabled daughter, and Jules who has mobility problems and suffers from anxiety. Mark thinks that coming together to support each other could be just what this group needs, with lots of laughter along the way.
