Vivian Campbell is the co-lead guitarist who replaced Steve Clark after his death. After filling Steve's shoes for years, he has a story of his own that fits with the name of Def Leppard. He started battling Hodgkin's Lymphoma (a type of cancer) recently. Instead of putting his health first, he decided not to cancel any shows and tour with cancer for his fans! It ended up in remission about half a year later! He is also a pescetarian.
