“I remember that during a rehearsal, I saw a perfect little girl running down the aisle at the Novello Theatre, singing at the top of her voice along with all of us on the stage. This was Rosie. She filled the room with her vibrance and her passion for music. Rosie’s Rainbow Fund now fills the room for others too. The fund has brought fun and love of music to so many. May the rhapsody built in her honour continue forever”
