Chicken Shack are a British blues rock band founded in 1965 by Stan Webb, Andy Silvester, and Alan Morley, who were later joined by Fleetwood Mac’s Christine McVie, then still known as Christine Perfect. She would leave the band somewhere in 1969 to join Fleetwood Mac, and was replaced by Paul Raymond of UFO and Michael Schenker Group fame. They signed to the legendary British blues label Blue Horizon in 1967.

100 Ton Chicken is the band's third studio album from 1969 and offers a nice balance of blues standards and originals penned by the band's only constant member Stan Webb, who is still active to this day. It features the single "Tears In The Wind" and a cover of Davey Graham’s folk masterpiece "Anji".

100 Ton Chicken is available as a limited edition of 750 individually numbered copies on green vinyl.
