The event, featuring songs from some of the West End’s biggest shows, will take place on stage at the city’s Hermon Arts Center on October 15.
It was organized by Danielle Edwards and her family and friends to raise money for the hospital treating her son, Joey.
The four-year-old, who suffers from an immune disorder, spent three and a half weeks there after surgery earlier this year and continues to receive regular treatment.
Having been in countless amateur dramatic productions, Danielle felt the musical theater extravaganza was the best possible way to help the hospital and give people a good night out.
It’s a real family affair with Danielle and her husband Eddie who live in Welshpool, Joey’s grandmother, godmother and close friends who perform on stage. Even Joey’s older brothers Sam and Ben, 9 and 11, will be involved, selling raffle tickets in the evening.
“They all saw the difficulties that Joey faced and continues to face in his life,” she said.
“Despite this, he is still so happy and smiling. Medical treatment is something you cannot do for your child yourself, but we had to do something. It will also help Joey, knowing that he is donating in the hospital and help him feel a little in control.”
“We know so many people whose children have been cared for in hospital – it really is a remarkable place and the staff there are amazing.”
She said the evening will feature hit songs from musicals from all decades, from Sound of Music and West Side Story to more recent hits from Shrek and Frozen.
“There will be lots of costumes, dancing and drama. We hope everyone has a great night.”
