A recording of a pair of 911 calls from David Crosby shows the Rock and Roll Hall of Famer sounding panicked as he repeatedly asks dispatchers how soon an ambulance will arrive to help a pedestrian he just hit with his car.

"He's on foot and he's hurt and we need an ambulance here right now," Crosby says in a recording of the first of two calls that was released Wednesday by the California Highway Patrol.

"I'm worried about him a lot," he can be overheard telling someone next to him.

Crosby was driving near his Santa Barbara County home on Sunday when the accident occurred.

He tells a dispatcher the sun was in his eyes and he couldn't see 46-year-old Jose Jimenez jogging on the same side of the road as his car.

Jimenez, who was hospitalized with broken bones, cuts and bruises, is expected to survive. Crosby was not hurt.

Authorities say the rock star was cooperative and neither drugs nor alcohol were involved in the crash.

After a dispatcher assures him an ambulance is on the way and tells him to stay in place Crosby hangs up. But then he calls back and speaks with another dispatcher.

"Is the ambulance on its way and how fast will it be here?" he asks. "I think this guy really needs an ambulance right now. "

Crosby, 73, is in the Rock and Roll Hall of Fame as a member of the Byrds and Crosby, Stills and Nash.
