Martin Dale Chambers (born 4 September 1951 in Hereford) is an English musician, who is best known as a founding member and drummer of the rock band the Pretenders.
 In addition to playing the drums with the group, Chambers sings backing vocals (lead vocals on the song "Fast or Slow (The Law's the Law)", the B-side of the singles "2000 Miles" and "Show Me", which he also wrote) and plays percussion.
 He was part of the original band line-up which also included Chrissie Hynde (vocals/guitar), James Honeyman-Scott (guitar/vocals/keyboards) and Pete Farndon (bass guitar/vocals).
 Hynde and Chambers are the only two surviving original members, and he has served two separate tenures with the group.
Christine Ellen "Chrissie" Hynde (born September 7, 1951) is an American musician who is best known as a founding member of the rock band The Pretenders.
The Pretenders are an English-American rock band formed in Hereford, England, in March 1978.
 The original band consisted of initiator and main songwriter Chrissie Hynde (lead vocals, rhythm guitar), James Honeyman-Scott (lead guitar, backing vocals, keyboards), Pete Farndon (bass guitar, backing vocals), and Martin Chambers (drums, backing vocals, percussion).
 Following the drug-related deaths of Honeyman-Scott and Farndon, the band has experienced numerous subsequent personnel changes, with Hynde as the only consistent member, and Chambers returning after an absence of several years.
Last of the Independents is the sixth album by rock group The Pretenders, released in 1994.
 For this album, the band is officially credited as being Chrissie Hynde (vocals, guitar), Adam Seymour (guitar), Andy Hobson (bass) and Martin Chambers (drums).
 However, this line-up only plays together on one track ("All My Dreams"); the rest of the album is performed by Hynde and Seymour in conjunction with a rotating series of musicians on bass and drums.
 These musicians include Hobson and Chambers, as well as bassists Andy Rourke, Tom Kelly and David Paton, and drummers Jimmy Copley and J.F.T. Hood.
 A few other session musicians also appear, including Ian Stanley, and one-time Pretenders guitarist Robbie McIntosh, who plays alongside Hynde and Seymour on "I'm a Mother".
Reckless: My Life as a Pretender is a memoir by the American musician Chrissie Hynde, a member of rock band The Pretenders.
 The book was published on September 8, 2015 by Doubleday, New York and London.
 In it, Hynde documents her childhood and youth in the Midwest, the founding of The Pretenders, life on the road and interactions with other musicians.
Packed!
 is the fifth album by rock group The Pretenders, released in 1990.
 For this album, the only real member of the group is Chrissie Hynde; no other person is pictured anywhere within the album package, and a rotating cast of session musicians (rather than a set band) is used to back Hynde throughout, essentially making this a de facto solo album by Hynde, only using the Pretenders name to satisfy contractual obligations.
 However, drummer Blair Cunningham plays on all tracks, though he is not credited as part of the band.
Cho Kyuhyun (better known by his mononym Kyuhyun) is a South Korean singer.
 His discography consists of one studio album, three extended plays, seven singles, three promotional singles, and seventeen soundtrack songs.
 He debuted as a member of South Korean boy band Super Junior in 2006 and subsequently became a part of its subgroup Super Junior-K.R.Y. in 2006 and Super Junior-M in 2008 as well as S.M. Entertainment's group SM the Ballad in 2010.
Cho Kyu-hyun (born February 3, 1988), better known mononymously as Kyuhyun, is a South Korean singer and musical theatre actor.
 He is best known as a member of South Korean boy group Super Junior, its sub-groups Super Junior-K.R.Y., Super Junior-M and a former member of the South Korean ballad group S.M. the Ballad.
 He is one of the first four Korean artists to appear on Chinese postage stamps.
Baggariddim, not to be confused with the EP Little Baggariddim released in the US, is the sixth album by UB40, released in 1985.
 Most of the tracks are reworkings of previous UB40 recordings that originally appeared on "Labour of Love" and "Geffery Morgan", here showcasing guest singers and "toasters" on vocals.
 Guest artists included Chrissie Hynde, the leader of The Pretenders, and Douglas Gilbert, lead trombonist with the London Symphony Orchestra (LSO).
