Country Joe Mc Donald Of Country Joe and The Fish

Joseph Allen McDonald (born January 1, 1942 in Washington, DC) was the leader and lead singer of the 1960s rock & roll group, Country Joe and the Fish.
He started his career busking on Berkeley, California's famous Telegraph Avenue in the early 1960s. His mother, Florence McDonald, served for many years on the Berkeley city council. As of 2007, Country Joe still lives in Berkeley.
Country Joe has recorded 33 albums and has written hundreds of songs over a career spanning 40 years. He and Barry Melton co-founded Country Joe and The Fish which became a pioneer psychedelic band with their eclectic performances at The Avalon Ballroom, the Fillmore, Monterey Pop Festival and Woodstock.
Their best-known song is his "The "Fish" Cheer / I-Feel-Like-I'm-Fixin'-To-Die Rag," a black comedy novelty song about the Vietnam War, whose familiar chorus ("One, two, three, what are we fighting for?") is well known to the Woodstock generation and Vietnam Vets of the 1960s and 1970s. He is also known for "The Fish Cheer" which was a cheerleader-style call-and-response with the audience where Joe spelled out "fish" ("Give me an F!").

Peter Green Of Fleetwood Mac

Peter Green (born Peter Allen Greenbaum, October 29, 1946, in Bethnal Green, London) is a British blues-rock guitarist and founder of the band Fleetwood Mac.
A figurehead in the British blues movement, Green inspired B. B. King to say, "He has the sweetest tone I ever heard; he was the only one who gave me the cold sweats." Green's playing was marked with a distinctively keen vibrato and economy of style, as well as a unique out of phase sound from his 1959 Gibson Les Paul Standard. He used a Fender Stratocaster on the track Albatross, and used a National resonator guitar on Oh Well Part I.

Keith Emerson Of ELP and the Nice

Keith Noel Emerson (born 2 November 1944 in Todmorden, Yorkshire) is a British keyboard player and composer. Formerly a member of The T-Bones, V.I.P.s, P.P. Arnold's backing band, and The Nice (which evolved from P.P.Arnold's band), he started Emerson, Lake & Palmer (ELP), one of the early supergroups, in 1970. Following the breakup of ELP, circa 1979, Emerson had modest success with Emerson, Lake & Powell in the 1980s. ELP reunited during the early 90s. Emerson also reunited The Nice in 2002 for a tour. He currently tours (through 2007) with The Keith Emerson Band. From Wikipedia
