David Walker (born 25 January 1945) is an English singer and guitarist who has been front-man for a number of bands; most notably The Idle Race, Savoy Brown and Humble Pie, he also served briefly with Fleetwood Mac and Black Sabbath.

Their first single, in 1963, was a cover of the pulsating Isley Brothers's "Shout" backed by "Little Things You Do" an original tune written by Dave Walker and Roy Brown.

Beckett played three days a week at the Rum Runner nightclub in Birmingham (which at the time was managed by Mick Walker), but they never recorded, and disbanded in late 1969.

The album was a commercial failure and in 1971 all members of the incumbent line-up with the exception of Masters (Walker, Hopkins, Pritchard, and Spencer) departed the band.

Ex-Blodwyn Pig/Juicy Lucy bassist Andy Pyle replaced Silvester by the next album Lion's Share (Parrot/Deram) for which Walker wrote "Denim Demon".

[5][11][12][13] Hungry Fighter only managed to play one live gig, at the University of Surrey in Guildford, England (which was not recorded), before the consequences of a road accident sustained by their crew following the gig (which included the destruction of the band's equipment and serious injuries sustained by one member of the road crew), combined with Kirwan's deteriorating mental health, caused the band to fold.

[15] Walker then moved to San Francisco and joined Raven; a band which in its short life had a revolving door of personnel but was fronted throughout by the late ex-Quicksilver Messenger Service guitarist John Cipollina.

No vocals were recorded with Walker, but the new line-up appeared on the BBC Midlands TV program "Look Hear" on 6 January 1978, performing their hit "War Pigs" plus an early version of what would eventually become "Junior's Eyes".

Geezer Butler thus resumed his traditional job as Black Sabbath's primary lyricist, and completely new lyrics for the album were written, including what became "Junior's Eyes".

After being out of the music business for eight years, in 1986 Kim Simmonds persuaded Walker to rejoin his revamped Savoy Brown, which included Al Macomber on drums and Jim Dagnesi on bass.

By the late 1990s Walker had relocated to Bozeman, Montana, where in 1999 he met up with an old friend from his San Francisco days, Ron Sanchez, who had (and still has) a psychedelic garage band called Donovan's Brain, who have an "open door" approach to personnel, jamming and making music.

Several tracks including Walker; that were left over from the TCLS sessions, were released in January 2003 on the Donovan's Brain album, The Great Leap Forward (Career Records).

The line-up of the band consists of Walker, Lewis, Chris Cundy (piano, keyboards, Hammond organ), Eddie Tsuru (bass), and Mike Gillan (drums).

Walker played tambourine on a track by The Nomads (who were working in the same studio as Donovan's Brain on 24 May 1999) called "Top Alcohol", which was the B-side to their "The King of Night Train" single (White Jazz Records).

In 2004, Walker also contributed vocals to a cover of "I'm Tired", on founder member of Savoy Brown John O'Leary's album Sins.

Musicians included members of Peter Green's Splinter Group, The Kinks, Downliners Sect (Don Craine and Keith Grant) and former Yardbird Ray Majors on lead guitar.

In Spring 2020, during COVID lockdown, Walker recorded the Black Sabbath song "The Wizard" under the band name Silver Sabbath (Dave Walker- vocals, Jerry Marotta-drums, Michael Visceglia-bass, Dennis Gruenling- electric harmonica, David Malachowski-guitar), filmed/recorded remotely from New York City, Woodstock, New Jersey, and Montana, edited by Jarek Zabcynski.
