Surely it's not possible to rehearse, stage, costume, choreograph, light, construct and perform a musical from scratch all in 48 hours, is it?

Well that's what Eyebrow productions are doing this October with their Showtime Challenge production of Me and My Girl. We at Three’s A Crowd quite like a challenge so we went all ‘jazz hands’ this weekend as we sent Anna Krahn to audition for a part in the show.

Here's how she got on.

Before journalism, musical theatre was my first love. I’d make my neighbours crazy with my incessant singing, my parents doolally with requests for ballet lessons and general strangers confused with my reciting lines to myself walking along the street.

But several years ago I decided that my singing should be reserved to the shower, my dancing to the clubs and my acting to, well, myself. This weekend I was reminded why.

Nervous doesn’t even come close to describing how I felt as I sat waiting to be called in. I’d prepared a song – Wouldn’t it be Loverly from My Fair Lady complete with cockney accent and a monologue from Noel Coward’s Blithe Spirit.

The acting came first and although I knew the monologue when I was in my room, walking down the street and even on the tube (Yes I encountered many odd looks and people shifting seats) I seemed to have left my memory on the Piccadilly line.

I walked in to stand in front of the director. A few lines in and I started blathering like an idiot. I apologised, composed myself and started again but it wasn’t happening. Luckily the director handed me a script which may have just pulled myself back in the game. Doing my best clipped Keira Knightley accent I haughtily acted out a scene as a gold digging socialite and, in my ever so humble opinion, think I rocked.

Next came the singing and as I sat in the waiting room I started envisioning Simon Cowell sitting behind the table. With visions of the gleaming-toothed menace watching me with a look of disdain I waited.
