Question: What professions did Bob Marley and Eric Bloom have in common?
Context: Eric Bloom (born December 1, 1944) is an American singer, songwriter and musician.  He is best known as a vocalist, and "stun guitar" player for the long-running band Blue Öyster Cult, with work on over 20 albums.  Much of his lyrical content relates to his lifelong interest in science fiction. Robert Nesta Marley, OM (6 February 1945 – 11 May 1981) was a Jamaican singer-songwriter, musician and guitarist who achieved international fame and acclaim, blending mostly reggae, ska and rocksteady in his compositions.  Starting out in 1963 with the group the Wailers, he forged a distinctive songwriting and vocal style that would later resonate with audiences worldwide.  The Wailers would go on to release some of the earliest reggae records with producer Lee "Scratch" Perry. Talkin' Blues is a live album by Bob Marley & The Wailers, released in 1991.  It contains live studio recordings from 1973 and 1975 intercut with interview segments of Bob Marley.  The majority of tracks are taken from the recordings Bob Marley & The Wailers did on 31 October 1973, at The Record Plant for San Francisco radio station KSAN.  They include "You Can't Blame the Youth", sung by Peter Tosh, and "Get Up, Stand Up" with Bob Marley and Peter Tosh alternatingly taking lead vocals.  The remaining songs are taken from a performance at The Lyceum Theatre in London and interview segments from Jamaican radio in 1975. Bob Marley and the Wailers were a Jamaican reggae band created by Bob Marley.  The band formed when self-taught musician Hubert Winston McIntosh (Peter Tosh) met Neville Livingston (Bunny Wailer), and Robert Nesta Marley (Bob Marley) in 1963 and taught them how to play guitar, keyboards, and percussion.  By late 1963 Junior Braithwaite, Beverley Kelso, and Cherry Smith had joined the Wailers.  After Peter Tosh and Bunny Wailer left the band in 1974, Bob Marley began touring with new band members.  His new backing band included brothers Carlton Barrett and Aston "Family Man" Barrett on drums and bass respectively, Junior Marvin and Al Anderson on lead guitar, Tyrone Downie and Earl "Wya" Lindo on keyboards, and Alvin "Seeco" Patterson on percussion.  The "I Threes", consisting of Judy Mowatt, Marcia Griffiths, and Marley's wife, Rita, provided backing vocals. "Black Blade" is a song by American rock band Blue Öyster Cult.  The lyrics were written by Eric Bloom and British science fiction writer Michael Moorcock from the viewpoint of Elric, Moorcock's most famous character.  Elric wields a sentient, soul-sucking sword named Stormbringer.  Aside from a set of cryptic, blood-red runes on the blade, the sword is black, hence the name "Black Blade".  The music was jointly composed by Eric Bloom, lead singer of Blue Öyster Cult, and bass-player John Trivers.  The song was featured in the Blue Öyster Cult album "Cultösaurus Erectus."  When Bloom was asked how he got in touch with Moorcock for the song he claims, "I went out of my way to send him a Fan Boy letter.  He was living in England, and he came over to America, to meet with his publisher.  He said, “Let's get together.”  We got together, and bonded, and he started sending me lyrics.  That is how "Black Blade," "Veteran of Psychic Wars" and "Great Sun Jester" happened. Marley is a posthumous two-disc soundtrack album by Bob Marley & The Wailers.  It was released by Island Records and Tuff Gong Records.  The soundtrack features music from the whole career of Bob Marley, his first recorded song, "Judge Not", to the last album he released in his lifetime, "Uprising".  "Marley" was released to coincide with the release of "Marley", a biographical film documenting the life of Bob Marley.  The album features 24 of the 66 tracks used in the film. Vincent Ford (c. 1940 – 28 December 2008), known as "Tata" or "Tartar", was a Jamaican songwriter best known for receiving writing credit for "No Woman, No Cry", the reggae song made famous by Bob Marley & The Wailers, as well as three other Bob Marley songs.  However, controversy persisted as to whether the compositions had actually been written by Marley himself, and had been credited to Ford to allow Marley to avoid contractual obligations, resulting in a legal battle that ended with the Marley estate being granted control of the songs. "Hammer" is a song by Bob Marley.  It was first recorded early in Marley's career (probably 1968) but never appeared on the Bob Marley & The Wailers studio albums in the seventies.  JAD Records ultimately released remastered versions of the early studio sessions of Bob Marley & Wailers; "Hammer" is included on "Fy-ah, Fy-ah" and a Sly and Robbie remix of the song is included on "Man To Man".  A version of the song also appears on the box-set "Songs of Freedom". The Bob Marley Museum is a museum in Kingston, Jamaica, dedicated to the reggae musician Bob Marley.  The museum is located at 56 Hope Road, Kingston 6, and is Bob Marley's former place of residence.  It was home to the Tuff Gong reggae record label which was founded by The Wailers in 1970.  In 1976, it was the site of a failed assassination attempt on Bob Marley.  The Chicago-based band 56 Hope Road takes its name in homage to the address. Bob Marley and the Wailers were a Jamaican reggae band led by Bob Marley which developed from the earlier ska vocal group, the Wailers, created by Marley with Peter Tosh and Bunny Wailer in 1963.  By late 1963 singers Junior Braithwaite, Beverley Kelso, and Cherry Smith had joined the Wailers.  By the early 1970s, Marley and Bunny Wailer had learned to play some instruments and brothers Aston "Family Man" Barrett (bass) and Carlton Barrett (drums), had joined the band.  After Bunny Wailer and Peter Tosh left the band in 1974, Marley began touring with new band members.  His new backing band included the Barrett brothers, Junior Marvin and Al Anderson on lead guitar, Tyrone Downie and Earl "Wya" Lindo on keyboards, and Alvin "Seeco" Patterson on percussion.  The "I Threes", consisting of Judy Mowatt, Marcia Griffiths, and Marley's wife, Rita, provided backing vocals.
