SAN RAFAEL, Calif. (AP) _ Rock promoter Bill Graham, killed last month in a helicopter crash, left his $15 million estate to relatives.

About 55 percent of the estate will be divided equally by his two sons, David Graham, 31, and Alexander Graham-Sult, 14. The remainder will be shared by Graham's four sisters, a nephew and a foster brother, according to court records filed Thursday.

Graham, 60, was killed with two other people Oct. 25.

Nicholas Clainos, president of Bill Graham Presents Inc., was appointed special administrator to manage Graham's business interests, investments and partnerships.

The company produced more than 500 concerts and theatrical productions a year. Graham founded the company in 1967, when he began promoting groups and artists such as the Grateful Dead, Carlos Santana and Janis Joplin.
