Andy Fraser, 62, the bassist for British blues-rock band Free who cowrote its mammoth 1970 anthem "All Right Now," died Monday in Temecula, Calif., where he lived.

The Riverside County coroner's office announced his death on its website, saying the cause had not been determined. In recent years, after coming out as gay, Mr. Fraser talked about having AIDS and the HIV-related cancer Kaposi's sarcoma.

Mr. Fraser was a teenager playing bass in John Mayall's Bluesbreakers when he helped form Free in 1968 with vocalist Paul Rodgers, guitarist Paul Kossoff, and drummer Simon Kirke. Mr. Fraser and Rodgers collaborated on writing songs for the band.

"All Right Now," released on the band's third album, featured Rodgers' rough vocals on suggestive lyrics, a distinctive bass solo by Mr. Fraser, and driving power chords. The song streaked to No. 4 on the U.S. charts in 1970 and turned into a classic rock staple. It has since been adopted by the Stanford University and University of Southern California marching bands and is played during sporting events. - L.A. Times
