BYRD Brain Crosby - Plans Own Funeral!

ROCK icon David Crosby is so sure he’s dying the Mr. Spaceman singer is planning his funeral — and desperately hoping his estranged Byrds and Crosby, Stills, Nash and Young bandmates will bury the hatchet and attend!

The 78-year-old Rock & Roll Hall of Fame member hasn’t spoken to Stephen Stills, 74, Graham Nash, 77, and Neil Young, 73, in years, but is hoping to mend fences.

“David can be brash and arrogant, but these guys still mean so much to him after working together for 50 years,” a source spills. “He doesn’t want to leave this earth on bad terms with them.

“He’d like to reconcile so they would attend his funeral.”

David believes the end is near. He has a slew of health problems, many related to his years as a boozer and cocaine-and-heroin druggie. He has hepatitis C, underwent a liver transplant, suffered heart attacks and has eight stents in his bum ticker.
