Charlotte Ritchie may have three best-selling albums and even an appearance in Harry Potter and the Goblet of Fire to her credit, but for her the chance to perform live is all that matters.

Ritchie is one member of the classical crossover quartet All Angels, who head to Epsom Playhouse this week as part of their UK tour.

And the 20-year-old admits the prospect of belting out a few hits fills her with genuine excitement.

Ritchie says: “Concerts always give me a real thrill as you know that people have come to see you and you alone.

“There is something different in a live show that you just cannot replicate on a recording.

“The atmosphere, the banter with the audience - there really is nothing like performing live.

“We all get a real buzz out of singing and we just cannot get enough of it.”

The foursome - Ritchie, Melanie Nakhla, Laura Wright and Daisy Chute, are all currently at university having teamed up as fresh-faced teenagers back in 2006.

The group were put together via an audition process by Universal, and Ritchie reveals it has been a somewhat unusual path to fame.

She continues: “When I went along for the first audition I really had no idea what it was for.

“I was slightly nervous anyway as my mum made me wear smart clothes and I never normally wear anything smart!

“The next thing I knew there was a second audition with Universal, then a month later we were in the studio recording and then a month after that we were doing photoshoots.

“Although we were put together unnaturally we feel very natural as a group.

“At first we were all a bit sheepish when we met but none of us are prima donnas and we all get on really well.”

That was 2006, and four years on the group are about to unleash their latest album, Fly Away, a collection of songs with an American feel.

And, despite having performances at the likes of the Royal Albert Hall, Wembley Stadium and even the set of Emmerdale already in the bag, Ritchie insists there is plenty more still to come.

She concludes: “We are all loving what we do and we want to keep singing as long as possible.

“My motto has always been to take life as it comes and I am still amazed at the opportunities we are given.

“The day playing at the likes of the Royal Albert Hall becomes boring is the day something has gone wrong, but I do not see that happening for some time yet.”
