It's such hard work doing a musical. I did my first musical last year, performing in The Producers, and it was a big part to suddenly be doing Leo Bloom in that. It's such hard work. It's a proper slog. It became like clocking in. And it's a big factory - you go in, everyone's got their little plot, people are taking in and out of it if they have days off or holidays, and it's just a jigsaw that all works. It always amazes me that this product would happen every night and it was just all these elements coming together in a big machine.
