Earlier, he told Ben and Andrew in the nest that he thought he should have been given the male lead role.
"I should have had that by a flipping mile," he exclaimed.
Ben assured him that he’s a better singer but Andrew disagreed and said that he thought David should have been given Mario’s part of second male role.
"I would have put Dave in first, probably Steve in second," said Ben.
"You third, Andrew fourth and the Mole last," David continued.
"We are basically flipping up the backend right? You’ve got the Baron and Rachel and you got Mario and Josie right? They’re the main parts."
Ben pointed out that they were ahead of Corin and John James who have been put on backing vocals.
"That doesn’t fill me with a lot of confidence," laughed David. "Have you heard John James and Corin singing? I could bring my cat down and put some chili on his tongue and it would fucking sing better than that."
Later, Mario joined them in the nest and David, making it clear he felt bitter about Stone's decision, challenged him to a singoff.
"We're gonna sing verse four. You sing it first then I’ll sing it and these boys will judge who’s the best."
