The tour is also renowned for its use of new technology; because of Bush's determination to dance as she sang, her stage sound engineer Martin Fisher rigged a wireless headset microphone using a wire clothes hanger, making her the first singer to use such a device on stage. The simple staging also involved rear-screen projection and the accompaniment of two male dancers. The tour was notable for the death of Bush's lighting engineer, Bill Duffield, to whom one of the London shows was dedicated.
