Three choirs with three very different stories come together at St Chad's Church, Shrewsbury, for 100 Voices — an evening of male-voice harmony in aid of Hope House.

Between them, these choirs span more than a century and a half of singing, from a Shropshire factory canteen and a Shifnal pub snug to the terraces of a Welsh rugby stadium, and tonight their very different traditions share a single stage. Here's who you'll be hearing.

Shrewsbury Male Voice Choir
Founded in the late 1950s by a group of Rolls-Royce workers in Shrewsbury who fancied a Christmas sing-song, SMVC has grown into one of the town's best-loved musical institutions, carrying that tradition forward for well over sixty years.

Shifnal & District Male Voice Choir
Shifnal's choir traces its roots to 1957, when a group of men gathered for a singsong in the town's White Hart pub. What began as an informal singalong soon became a weekly fixture, and nearly seventy years on it remains a cornerstone of east Shropshire's musical life

Côr y Sgarlets (formally Llanelli Male voice Choir)
Côr y Sgarlets — the Scarlets Choir — is Llanelli's rugby-born choir, forever associated with Stradey Park and its successor ground, Parc y Scarlets. Formed within Llanelli's passionate choral culture, in a town where song and rugby have long gone hand in hand, the choir became famous for filling stadiums with Sospan Fach and Hen Wlad Fy Nhadau on matchdays, most memorably at the emotional final game at Stradey Park in 2008, when the choir's singing sent the old ground into its closing chapter to a standing ovation.
