Last year’s X Factor semi-finalist boy band Union J have been confirmed as additional main stage guest performers at this year’s Sundown Festival.

The band, comprising Josh Cuthbert, Jamie ‘JJ’ Hamblett, James ‘Jaymi’ Hensley and George Shelley, became a four-piece during the X Factor series when then soloist Shelley joined the others.

It was announced in January that Union J had signed a record deal with Sony Music, with an anticipated debut single due out in June of this year.

Set to perform on the Sunday of Sundown, Union J joins the previously confirmed line-up of main stage weekend headliners Jessie J and Example, with JLS, DJ Fresh and James Arthur also performing at the festival, and with Rinse and Hospitality hosting Stage 2.

Sundown Festival spokesperson, Dion Clements comments: “Union J are very possibly one of the most popular and hotly anticipated X Factor acts not to have reached the final, so we’re very pleased to have them performing at Sundown”.
