Authorities say Lee Dorman, the bassist of psychedelic rock band Iron Butterfly, has died at age 70.

Orange County Sheriff's Department spokeswoman Gail Krause says Dorman was found dead in his car Friday morning, at his home in the coastal Southern California town of Laguna Niguel.

According to coroner's officials, foul play is not suspected. Dorman died of natural causes in Southern California and there won't be an autopsy.   A statement from the Orange County coroner's office said Dorman had been under the care of a physician. Authorities said he may have been on his way to a doctor's appointment when he died.

No services have been announced.   Douglas Lee Dorman was born in September 1942.

Iron Butterfly rose to prominence in the late 1960s. According to the band's website, its second album, In-A-Gadda-Da-Vida, sold more than 30 million copies. The title track's distinctive notes have been featured in numerous films and TV shows including The Simpsons, That `70s Show and in the series finale of Rescue Me.

Dorman was also a founding member of the rock group Captain Beyond.
