The final 50 boys, who have passed the audition and callback stage will enter Joseph School, where a team of the best coaches in the business teach them vocals, acting and choreography.

With every boy getting the very best in training, there’s some unexpected blossoming of talent, but viewers also see those who can’t hack the pace and, as the drama unfolds, more dreams are made and broken.

The intense Joseph School workshops also include celebrity mentors such as Jason Donovan popping in to lend their support and advice on what it takes to make it as a Joseph. In addition, the panel give the boys nightly progress reports and dreaded overnight homework tasks.

Andrew Lloyd Webber is also on hand to drop a few bombshells as he realises that turning a completely untrained voice into one that can handle eight shows a week is again going to be harder than he thought. Has he cast his net too wide? Can a builder really be the next Joseph?

“The character of Joseph is very difficult to cast,” says Andrew. “He has to be nauseatingly gorgeous so you understand why the brothers throw him in the pit and we have to be convinced of the journey he goes on and the value of forgiveness. It’s a tough call.”
