British rocker died in December at age 70

Lemmy Kilmister, the Motorhead bassist and vocalist who died Dec. 28 at age 70, died of prostate cancer and congestive heart failure, according to health department papers obtained by TMZ.

The musician, whose real name was Ian Fraser Kilmister, died after a brief battle with “an extremely aggressive cancer,” the band said on its official Facebook page following his death last month.

“There is no easy way to say this … our mighty, noble friend Lemmy passed away today after a short battle with an extremely aggressive cancer,” the message read.

“He had learnt of the disease on Dec. 26th, and was at home, sitting in front of his favorite video game from The Rainbow which had recently made its way down the street, with his family. We cannot begin to express our shock and sadness, there aren’t words.”

A memorial for the musician, known for high-speed, high decibel tunes such as “Ace of Spades,” was held Jan. 9 at Forest Hills Cemetery, with a livestream for fans who couldn’t attend the service, along with a rocking celebration of his life the Rainbow Bar & Grill on Sunset Blvd. in West Hollywood.
