Problem: Background: David was born in Southampton, Hampshire, the son of Tina (nee Loftus), a retail assistant at Superdrug, and George David, a carpenter, and grew up in the Holyrood estate. David's father is Afro-Grenadian and David's mother is Anglo-Jewish and related to the founders of the Accurist watch-making company; David's maternal grandfather was an Orthodox Jew and his maternal grandmother a convert to Judaism. David's parents separated when he was eight and he was brought up by his mother. He attended Bellemoor School and Southampton City College.
Context: David later signed on with Warner Music and put together his third album, The Story Goes..., which was released worldwide in August 2005 (excluding the U.S. where it was never released). The first single, "All the Way", returned him to the top 3. The second single, "Don't Love You No More (I'm Sorry)", tied with "7 Days" as his longest-running single in the charts since "Re-Rewind", spending 15 weeks inside the UK top 75. The album's third single, "Unbelievable", debuted at number 18 in March 2006.  In 2007, David collaborated with British rapper Kano on his album London Town, for the single "This Is the Girl". The track was released on 27 August 2007 and debuted at number 18 on the UK charts.  The first single from his album Trust Me, "Hot Stuff (Let's Dance)", was released on 5 November 2007. David successfully sought permission from David Bowie to sample his 1983 number-one single "Let's Dance". The single was a top ten hit, whilst the album charted at number 18 on the UK Albums Chart. "6 of 1 Thing", the second single to be taken from Trust Me, charted at number 39 on the UK Singles Chart, becoming his third-lowest-charting single to date.  "Officially Yours" was released on 23 June 2008 and peaked at number 158 on the UK Singles Chart, becoming his lowest-charting single to date and was the final single from Trust Me. In July, a new track titled "Are You Up for This" started receiving airplay on various radio stations as part of a promo with Ice Cream Records, which also featured a remix with Wittyboy called "Nutter Butter". On 17 August 2008, David performed at a birthday tribute concert for songwriter Don Black at the London Palladium. He performed the song "Ben", originally a hit for Michael Jackson.  David took part in Soccer Aid 2008 at Wembley Stadium on 7 September 2008. He picked up the "Man of The Match" award on the night and played in the same England side as ex-internationals such as Alan Shearer, Teddy Sheringham and David Seaman, and played against the likes of Romario, Paolo Di Canio, Jaap Stam, and Luis Figo. David received two 2008 UK Urban Music Award nominations for Best Album with Trust Me and Best R&B Act. On 7 November 2008, David was recognised for his contribution to the music industry by receiving an honorary degree of Doctor of Music, from Southampton Solent University at a graduation ceremony held at Southampton Guildhall.
Question: Was there any notable events in 2006?
Answer: The album's third single, "Unbelievable", debuted at number 18 in March 2006.

Problem: Background: A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers.
Context: Five-piece bands have existed in rock music since the development of the genre. The Beach Boys, The Rolling Stones (until 1993), Aerosmith, Def Leppard, AC/DC, Oasis, Pearl Jam, Guns N' Roses, Radiohead, The Strokes, The Yardbirds, 311 and The Hives are examples of the common vocalist, lead guitar, rhythm guitar, bass, and drums lineup whilst other bands such as Judas Priest have two guitarists who equally share lead and rhythm parts. An alternative to the five-member lineup replaces the rhythm guitarist with a keyboard-synthesizer player (examples being the bands Journey, Elbow, Dream Theater, Genesis, Jethro Tull, The Zombies, The Animals, Bon Jovi, Yes, Fleetwood Mac, Marilyn Manson and Deep Purple, all of which consist of a vocalist, guitarist, bassist, keyboardist, and a drummer) or with a turntablist such as Deftones, Hed PE, Incubus or Limp Bizkit.  Alternatives include a keyboardist, guitarist, drummer, bassist, and saxophonist, such as The Sonics, The Dave Clark 5, and Sam the Sham and the Pharaohs. Another alternative is three guitarists, a bassist and a drummer, such as Foo Fighters, Radiohead, and The Byrds. Some five-person bands feature two guitarists, a keyboardist, a bassist and a drummer, with one or more of these musicians (typically one of the guitarists) handling lead vocals on top of their instrument (examples being Children of Bodom, Styx, Sturm und Drang, Relient K, Ensiferum and the current line up of Status Quo). In some cases, typically in cover bands, one musician plays either rhythm guitar or keyboards, depending on the song (one notable band being Firewind, with Bob Katsionis handling this particular role).  Other times, the vocalist will bring another musical "voice" to the table, most commonly a harmonica or percussion; Mick Jagger, for example, played harmonica and percussion instruments like maracas and tambourine whilst singing at the same time. Keith Relf of the Yardbirds played harmonica frequently, though not often while also singing. Ozzy Osbourne was also known to play the harmonica on some occasions (i.e. "The Wizard" by Black Sabbath). Vocalist Robert Brown of lesser known steampunk band Abney Park plays harmonica, accordion, and darbuka in addition to mandolin. Flutes are also commonly used by vocalists, most notably Ian Anderson of Jethro Tull and Ray Thomas of the Moody Blues, though these are difficult to play while singing at the same time.  A less common lineup is to have lead vocals, two guitarists of varying types and two drummers, e.g. Adam and the Ants.
