Question: Donald Christopher Barber (born 17 April 1930) is an English jazz musician, best known as a bandleader and trombonist. As well as scoring a UK top twenty trad jazz hit, he helped the careers of many musicians, notably the blues singer Ottilie Patterson, who was at one time his wife, and vocalist/banjoist Lonnie Donegan, whose appearances with Barber triggered the skiffle craze of the mid-1950s and who had his first transatlantic hit, "Rock Island Line", while with Chris Barber's band. His providing an audience for Donegan and, later, Alexis Korner makes Barber a significant figure in the British rhythm and blues and "beat boom" of the 1960s.

The 2017 line up is; Chris Barber and Bob Hunt (trombones); Mike Henry and Pete Rudeforth (trumpets), Bert Brandsma, Nick White and Ian Killoran (clarinets and alto sax, tenor sax, baritone sax). John Watson (drums), John Day (double bass), Joe Farler (banjo & guitar) Pat Halcox, trumpeter with the Chris Barber Band since 31 May 1954, retired after playing his last gig with the Big Chris Barber Band on 16 July 2008. Halcox and Barber were together in the band for 54 years - the longest continuous partnership in the history of jazz, exceeding even that of Duke Ellington and Harry Carney (48 years between 1926 and 1974). Tony Carter (reeds) also left the band at this time. Vic Pitt (double bass) retired in January 2007 after 30 years with the band. His feature duet with the drummers of the day - "Big Noise From Winnetka" was not only a feature of the Barber concerts, but also his time with the Kenny Ball band immediately before. When Amy Roberts joined the band in 2011, she was still a student at Royal Northern College of Music and thus not always able to be present. On several tours Bert Brandsma (reeds) replaced her. Brandsma joined as a permanent member in 2012. At St Luke's, London, on 9 June 2007 Barber appeared in the horn section of Nick Lowe's band during a concert. In 2008 Barber, along with Eric Clapton and others, were involved in a new co-operative record company, Blues Legacy. On 23 July 2009, Barber, Bilk and Ball played a one-off concert at Indigo2 at the O2 in Greenwich. The concert was presented by the British Music Experience. He performed at De Doelen in Rotterdam, the Netherlands, on 12 December 2010.

Question: Steely Dan is an American rock band founded by core members Walter Becker (guitars, bass, backing vocals) and Donald Fagen (keyboards, lead vocals) in 1972. Blending elements of jazz, traditional pop, R&B, and sophisticated studio production with cryptic and ironic lyrics, the band enjoyed critical and commercial success starting from the early 1970s until breaking up in 1981. Throughout their career, the duo recorded with a revolving cast of session musicians, and in 1974 retired from live performances to become a studio-only band. Rolling Stone has called them "the perfect musical antiheroes for the Seventies".

The Royal Scam was released in May 1976. Partly because of Carlton's prominent contributions, it is the band's most guitar-oriented album. It also features performances by session drummer Bernard Purdie. The album sold well in the U.S.A., though without the strength of a hit single. "Haitian Divorce" (Top 20) drove sales in the UK, becoming Steely Dan's first major hit in that country. Steely Dan's sixth album, the jazz-influenced Aja, was released in September 1977. Aja reached the Top Five in the U.S. charts within three weeks, winning the Grammy award for "Engineer - Best Engineered Recording - Non-Classical." It was also one of the first American LPs to be certified 'platinum' for sales of over 1 million albums. Featuring Michael McDonald's backing vocals, "Peg" (No. 11) was the album's first single, followed by "Josie" (No. 26) and "Deacon Blues" (No. 19). Aja solidified Becker's and Fagen's reputations as songwriters and studio perfectionists. It features such jazz and fusion luminaries as guitarists Larry Carlton and Lee Ritenour; bassist Chuck Rainey; saxophonists Wayne Shorter, Pete Christlieb, and Tom Scott; drummers Steve Gadd, Rick Marotta and Bernard Purdie; pianist Joe Sample and ex-Miles Davis pianist/vibraphonist Victor Feldman and Grammy award-winning producer/arranger Michael Omartian (piano). Planning to tour in support of Aja, Steely Dan assembled a live band. Rehearsal ended and the tour was canceled when backing musicians began comparing pay. The album's history was documented in an episode of the TV and DVD series Classic Albums. After Aja's success, Becker and Fagen were asked to write the title track for the movie FM. The movie was a box-office disaster, but the song was a hit, earning Steely Dan another engineering Grammy award. It was a minor hit in the UK and barely missed the Top 20 in the U.S.A.
