A selection of contestant quotes appear below:

Martin Lewis

“I don’t listen to music. I don’t sing. I’ve never been in a choir. And I’ve said no to lots of TV talent show type programmes. Yet my little girl loves musicals, and so I’ve been watching them with her; and when I mentioned that I’d been asked to do All Star Musicals, she got very excited. And I love my little girl, and I love a challenge. So I’m going to try and take my vocal chords to places they’ve never been before!”

Daniel Brocklebank

"My motivation for doing the show was to do something that took me out of my comfort zone. Coronation Street is such a wonderful place to work and as a result you feel very safe. You know the cast & crew inside out as we all work together every day. This sort of show breaks all those rules & forces you in to a new situation.

Also I love singing. I sing at home all the time but in 25 years of being an actor I’ve never really used my voice in this way. It’s always good to try something new & push your boundaries."

The main challenge for me will be the staging of it I think. Singing & dancing at the same time takes a huge amount of stamina. And as I can’t dance... I’m hoping I don’t have to do too much of it..."

London Hughes

“Since I was a kid I’ve always wanted to be in a musical! I used to spend hours in my living room dancing around and performing for my Teddybears. Now I get to perform for industry professionals, the Palladium audience and millions of people watching at home! Yep, no pressure then.”

Alan Titchmarsh

"I've always loved musicals and while I have always resisted taking part in any 'reality' TV shows I found the chance of being able to sing on the stage of the London Palladium irresistible. That said, I'm now scared stiff! I sang as a boy in the church choir and later as an adult, but I have never sung anything like this in public. Eeek!"

Tessa Peake Jones

“I was keen to do this because I wanted to be shaken out of my comfort zone and boy am I being shaken!!!

I’m really excited about the Palladium and being part of a team musically with an ensemble as I’ve never had that experience!

The challenge at the moment is pacing my breath and vocal chords for the duration of the song and I will NEVER say musicals are easy from now on! How little I knew!”
