"Who are Nick Cave, Ian Dury and Jarvis Cocker?   I've never heard of any of them."

Neither had I. But I've looked them up. FYI it would appear that:

Nick Cave (born in the late 1950s in central Missouri, USA) is an American fabric sculptor, dancer, and performance artist. He is best known for his Soundsuits: wearable fabric sculptures that are bright, whimsical, and other-worldly.

Ian Dury is a Computer Software Professional in Milton Keynes, United Kingdom

Jarvis Cocker is an English musician and former frontman for a popular beat combo.
