Question: Were Marc Bolan and Thom Yorke both members of the band Radiohead?
Context: Thomas Edward Yorke (born 7 October 1968) is an English musician and composer best known as the singer and principal songwriter of the alternative rock band Radiohead.  A multi-instrumentalist, Yorke mainly plays guitar and piano and works extensively with synthesisers, sequencers and programming.  He is known for his falsetto vocals; in 2008, "Rolling Stone" ranked him the 66th greatest singer of all time. Dead Children Playing (first edition titled 'Dead Children Playing: A Picture Book') is a picture book by Stanley Donwood and Thom Yorke (under the alias of "Dr. Tchock") featuring artwork that has been used on English alternative rock band Radiohead's albums between 1996 and 2003, and on Thom Yorke's album "The Eraser".  The book also contains works of art that have not previously been released, made between 1999 and 2005. Tomorrow's Modern Boxes is the second solo album by Thom Yorke of the English alternative rock band Radiohead, released on 26 September 2014.  It was produced by Radiohead producer Nigel Godrich, with artwork by Radiohead artist Stanley Donwood.  The album blends Yorke's vocals and piano playing with electronic beats and textures. Marc Bolan ( ; born Mark Feld; 30 September 1947 – 16 September 1977) was an English singer-songwriter, musician, guitarist, and poet.  He was best known as the lead singer of the glam rock band T. Rex.  Bolan was one of the pioneers of the glam rock movement of the 1970s.  He died at age 29 in a car accident a fortnight before his 30th birthday. Headless Chickens were a melodic punk band from Exeter, England whose members included Thom Yorke (guitar and vocals), Simon Shackleton (bass and vocals), John Matthias (violin), Laura Forrest-Hay (violin), Martin Brooks (drums), Andy Hills (bass) and Lindsey Moore (drums).  In June 1989 they released their first single, "I Don't Want To Go To Woodstock", on the "Hometown Atrocities" EP, along with tracks from three other bands (Beaver Patrol, Jackson Penis and Mad At The Sun).  This is believed to be Thom Yorke's first ever released recording, on which he played lead guitar and sang backing vocals; Yorke later became famous as the singer of Radiohead. Stanley Donwood (born 29 October 1968) is the pen name of English artist and writer Dan Rickwood.  He is best known for his work with the English alternative rock band Radiohead, having created all of their album and poster art since 1994, often in collaboration with Radiohead singer Thom Yorke.  He also creates artwork for Yorke's solo albums and Yorke's band Atoms for Peace. The Eraser is the debut solo album by Thom Yorke of the English alternative rock band Radiohead, released on 10 July 2006 on the independent label XL Recordings.  It was produced by longtime Radiohead producer Nigel Godrich.  The album comprises electronic music Yorke recorded during Radiohead's 2004 hiatus and between their 2005 rehearsals, and makes heavy use of original samples. Nigel Timothy Godrich (born 28 February 1971) is an English record producer, recording engineer and musician.  He is best known for his work with the English rock band Radiohead, having produced all of their studio albums since "OK Computer" (1997); he has been dubbed the "sixth member" of the band, in an allusion to George Martin being called the "Fifth Beatle".  Godrich has also worked extensively with Radiohead singer Thom Yorke on his solo material, and is a member of the bands Atoms for Peace (with Yorke) and Ultraísta.  Other acts Godrich has worked with include Beck, Paul McCartney, U2, R.E.M. and Roger Waters.  He is the creator of the music webseries "From the Basement". Kid A is the fourth studio album by the English rock band Radiohead, released on 2 October 2000 by Parlophone.  On the verge of a breakdown after promoting Radiohead's 1997 album "OK Computer", songwriter Thom Yorke envisioned a radical change in direction.  Radiohead replaced their rock sound with synthesisers, drum machines, the ondes Martenot, string orchestras and brass instruments.  They incorporated influences from genres such as electronic music, krautrock, jazz, and 20th-century classical music.  They recorded "Kid A" with "OK Computer" producer Nigel Godrich in Paris, Copenhagen, Gloucestershire and their hometown Oxford, England.  The sessions produced over 20 tracks, and Radiohead split the work in two albums: "Kid A" and "Amnesiac".  The latter was released the following year. "High and Dry" is a song by the English alternative rock band Radiohead, released as the first single from their second studio album "The Bends" (1995).  It was released as a double A-side with album opener "Planet Telex".  "High and Dry" was released in the UK on 5 March 1995.  Thom Yorke had performed an early version of the song with the band Headless Chickens while he was a student at University of Exeter in the late 1980s.  Radiohead later recorded a studio version of "High and Dry" during the sessions which produced the song "Pop Is Dead" in 1993, but the band dismissed it as a "Rod Stewart song".  During recording sessions for "The Bends," the band's demo recording of the song was rediscovered and remastered for inclusion on the album, as it was felt that it worked well with the rest of the album's music.  In a 2007 interview with Pitchfork Media, Yorke stated that he did not like the song, saying "It's not bad... it's very bad".  He also stated that he had been pressured into including the song on "The Bends".
