Emma had hoped to be well enough to attend the concert, but died in June, aged 43, after battling breast cancer.
Steven said: "Primarily, the event is to celebrate five years of The Queen's Centre, but it is also to raise money for the complementary therapy programme.
"The programme is a wonderful thing – they do all sorts of different therapies for patients, which go hand-in-hand with the medical treatment.
"It helps you cope with things a lot better.
"Emma had reflexology, where they massage parts of your feet relating to different parts of your body.
"She'd been very tired with some of her treatment, but after the reflexology she was walking on air."
A range of therapies are available, including different forms of massage.
Steven said: "I don't think some people know what it is, or understand why patients need it, so hopefully the concert will raise awareness too."
