Coope Boyes and Simpson

Their sound was rich and often had unusual vocal harmonies.The group comprised singers Barry Coope, Jim Boyes (formerly of Swan Arcade) and Lester Simpson, and almost all of their music was sung entirely a cappella, although they occasionally used accordion, guitar and drums very sparingly on recordings.

[1] They performed a mixture of both traditional folk songs (though often creatively arranged), hymns and carols, and their own original compositions.

Their Christmas recordings are sometimes accredited to 'Voices at the Door', while the trio was also part of the occasional supergroup Blue Murder along with members of Waterson–Carthy and The Watersons.

In December 2014 two members of the trio, Coope and Simpson toured with Jo Freya and Fi Fraser with a show of Christmas songs.

Since 2005 they frequently collaborated with label mates Chumbawamba, contributing vocals on their albums A Singsong and a Scrap, Get On With It!
