Debbie has written music from a young age when she would write pop songs for her rock group Firebird which she formed at school. She studied orchestration at the Royal College of Music and went on to write music for radio commercials and corporate films, arranging the music for various instrumental groups and singers and overseeing the recording sessions. Debbie's love of musicals and involvement with youth theatre, inevitably culminated in writing musicals for children to perform. She was commissioned by Walthamstow Primary School to write the music for Alice in Wonderland which was her first musical. Some years later, Debbie revisited the show and did her own adaption of Lewis Carroll's novel for another production of the show at her theatre school Centre Stage. This show has since been performed by several other schools. The score features a rapping White Rabbit, a calypso carnival Caterpillar, and various solos, ensemble numbers and dances.
