Keith Jack, 19

A supermarket customer service assistant and student from Dalheith, Midlothian.

Keith currently works as a customer assistant at Tesco’s while he is studying for an HNC in Musical Theatre at a college in Edinburgh.

His first public performance was at the age of five to residents at a retirement home, and he has since gone on to win various local singing competitions.

He thinks that he would be a “funny” Joseph, and surprise people with his powerful voice.

Keith first auditioned in Glasgow and says that he has loved being involved because “I’ve got to work with the best people in the business”.
