Singer Justin and guitarist Dan's mother and sister already have the painful condition and it's feared the two brothers are next in line.
Justin says, "It's genetic, so I suppose my fingers could seize up. It wouldn't be a strong look - a catsuit and a wheelchair.
"I also have friends with rheumatoid arthritis and it's a crippling, degenerative condition and a real pain in the a***.
"But the threat of the disease, or discovering I had it, won't stop me and won't keep me down."
The Darkness have put their weight behind British charity ARTHRITIS RESEARCH CAMPAIGN, which is raising money to find a cure.
The group has signed a guitar as a prize and hope the money raised will help relieve the pain of thousands across the UK.27/08/2004 14:17
