Jefferson Starship guitarist Mark “Slick” Aguilar has recently been diagnosed with Hepatitis C and is currently in need of a liver transplant. His band has helped set up a PayPal account where fans can donate and help Aguilar raise funds for the transplant. A message on their Facebook page says, “Mark ‘Slick’ Aguilar needs a liver transplant asap! Insurance only covers so much and there are many additional costs. Please help if you can, every little bit makes a difference.” Fans can click here to donate.

Aguilar’s resume includes stints with Wayne Cochran, Buddy Miles and David Crosby as well as KC & the Sunshine Band. He joined Jefferson Airplane singer Marty Balin’s solo group in 1985 and participated in the Airplane offshoot KBC Band in the ‘80s. Since 1992 he has been a member of Jefferson Starship.
