As stated in reply to a comment from tastewar, I am giving a listen to Dark Was the Night: A Red Hot Compilation. The album was produced in 2009 to raise money to fight AIDS.
In 1991, Prue’s friend Cynthia O’Neal founded Friends in Deed* with Mike Nichols to provide direct support for AIDS patients. The story of Friends in Deed is told in Cynthia’s memoir, Talk Softly, dedicated to her sons Max and Fitz. Prue says that Max has since passed away.
* The organization is now part of The Big Groups.
