Wickham was an assistant producer of the 1960s British television show Ready Steady Go!, and was fashion consultant for the short-lived "The Mod's Monthly" magazine, first issued in March 1964 by Albert Hand Publications, and edited by Mark Burns. However she is probably best known as the manager of well-known pop/soul acts Dusty Springfield and Labelle.
Wickham co-wrote (with Simon Napier-Bell) the English lyrics to Springfield's only British #1 hit, "You Don't Have to Say You Love Me", adapted from the Italian song Io che non vivo senza te. With Penny Valentine, she co-wrote Dancing with Demons, a biography of Dusty Springfield.
Wickham was given a Music Industry "Woman of the Year Lifetime Achievement Award" in 1999, and was appointed an Officer of the Order of the British Empire (OBE) in the 2013 Queens' Birthday Honours List, for services to music.
