A school assembly hall reverberated to the foot-stomping sound of an American blues band.

The Groanbox Boys performed at Thornton Grammar School, Bradford, during their three-month tour of the UK.

The trio of Cory Seznec, Michael Ward-Bergeman and Paul Clifford reeled off upbeat tunes and told the watching children about the origins of blues music.

Percussionist Paul said: “We get a great response from the children – we have been having a lot of fun.”
