A year ago, Gregg Allman underwent a liver transplant after his own liver was damaged due to his Hepatitis C.

 Now, the rocker is starting a campaign to help raise awareness about the disease and to kick it off, he and The Allman Brothers Band performed a benefit concert in New York last night (7/27), the eve of World Hepatitis Day.  Gregg told us about what happened when he first found out he had the disease and what we can do to prevent it.
