The Beau Brummels

The Beau Brummels were an American rock band. Formed in San Francisco in 1964, the band's original lineup included Sal Valentino (lead vocals), Ron Elliott (lead guitar), Ron Meagher (bass guitar), Declan Mulligan (rhythm guitar, bass, harmonica), and John Petersen (drums). They were discovered by local disc jockeys who were looking to sign acts to their new label, Autumn Records, where Sylvester Stewart—later known as Sly Stone—produced the group's early recording sessions. Initially, the band's musical style blended beat music and folk music and typically drew comparisons to The Beatles, while their later work incorporated other music genres such as psychedelic rock and country rock.
