Problem: Andrew Gary Johns (born 19 May 1974) is an Australian former professional rugby league footballer of the 1990s and 2000s. He is considered by many to be one of the greatest players of all time. Hailed as the best halfback in the world for many years, he captained the Newcastle Knights in the National Rugby League and participated in the team's only two premiership victories in 1997 and 2001, playing a club record 249 games for the Knights. Johns also represented his country at two World Cups, and on one Kangaroo tour, playing in total 21 Test matches for the national side.

Andrew Johns broke one of the longest-standing records in Round 2 of the 2006 season as he amassed 30 points against the Canberra Raiders and in doing so claimed the points-scoring record for a player at a single club, surpassing Mick Cronin's 1,971 points for Parramatta. Back in the NRL, playing for Newcastle during a Round 18 match against the Parramatta Eels, Johns' name entered the NRL record books for the second time in the year. A Johns conversion of a Newcastle try made Johns the highest points scorer in the 98-year history of first-grade rugby league in Australia, eclipsing Jason Taylor's previous record of 2,107 points. He rather coincidentally scored the record-breaking conversion in a 46-12 loss to the Eels, who were coached at the time by Jason Taylor. Things did not start well for Johns in the 2007 season as he lasted only four minutes into Round 1. As Canterbury Bulldogs forward Sonny Bill Williams went to perform one of his trade-mark hits on Johns, the tackle strayed high leaving Johns lying concussed. Williams pleaded guilty at the judiciary to a reckless high tackle, and received a two-week suspension for the hit. Johns missed the following match but returned in Round 3 against the Canberra Raiders--which would be his last career match in the NRL. On the Thursday after the Canberra match, a tackle with Newcastle teammate Adam Woolnough in a training session resulted in his referral to a specialist to examine a neck injury. It was revealed that Johns had a bulging disc in his neck. It was confirmed that this had been present for some time and was not related to the training incident. All medical advice was that Johns should retire from professional football, since any further neck injury could prove life-threatening and on 10 April 2007, Johns announced his retirement from rugby league. The Newcastle Knights' season would fall apart: they finished 15th of 16 teams on the ladder, narrowly missing out on the Wooden Spoon with a narrow two-point victory in their last match of the season. Johns tried to soften the blow of his retirement by saying he had been seriously considering retirement at the end of the 2007 season and was quoted in the press as saying "I knew this year would be my last year, it's just unfortunate it's stopped five months before the end of the season." Commenting on his teammates' reaction to his retirement, Johns noted: "They were sort of relieved I think, after a couple of injuries this year ... I think the time's right." On his retirement a chorus of past league greats called for Johns to be immediately honoured as an immortal of the game. In the preceding 13 years, the former Cessnock junior had changed the game like few others before him. On October 2008 Johns completed a walk from Newcastle to Sydney to raise funds for the Black Dog Institute.

Question:
Blur are an English rock band formed in Colchester in 1988. The group consists of singer/keyboardist Damon Albarn, guitarist/singer Graham Coxon, bassist Alex James and drummer Dave Rowntree. Their debut album Leisure (1991) incorporated the sounds of Madchester and shoegazing. Following a stylistic change influenced by English guitar pop groups such as the Kinks, the Beatles and XTC, Blur released Modern Life
After 13 and the subsequent tours in 1999-2000, band members pursued other projects. Graham Coxon recorded a string of solo albums, while Damon Albarn dedicated his time to Gorillaz, the animated band he had created with Jamie Hewlett. Alex James worked with Fat Les and co-wrote several songs with Sophie Ellis-Bextor and Marianne Faithfull. Recording for Blur's next album began in London in November 2001, but concerted work started in June 2002, with the sessions moving to Marrakech, Morocco soon after, and then to Devon back in the UK. Not long after the sessions began, Coxon left the group. Coxon said "there were no rows" and "[the band] just recognised the feeling that we needed some time apart". Before the album was released, Blur released a new single, "Don't Bomb When You Are the Bomb" as a very limited white label release. The song is largely electronic, and was part of the band's protest against war in the Middle East. Albarn, however, attempted to assuage fans' fears that the album would be electronic by providing reassurances that the band's new album would be "a rockin' record", and also said that it has "a lot of finely crafted pop songs". Early in 2002, Blur recorded a song that would be played by European Space Agency's Beagle 2 lander once it touched down; however, attempts to locate the probe after it landed on Mars were fruitless. Think Tank, released in May 2003, was filled with atmospheric, brooding electronic sounds, featuring simpler guitar lines played by Albarn, and largely relying on other instruments to replace Coxon. The guitarist's absence also meant that Think Tank was almost entirely written by Albarn. Its sound was seen as a testament to Albarn's increasing interest in African and Middle Eastern music, and to his complete control over the group's creative direction. Think Tank was yet another UK number one and managed Blur's highest US position of number 56. It was also nominated for best album at the 2004 Brit Awards. The band did a successful tour in 2003, with former Verve guitarist Simon Tong filling in for Coxon. In 2005, XFM News reported that Blur would record an EP, and denied that they would hire a replacement guitarist for Coxon. There were also some aborted recordings made in 2005. Overall the band kept a low profile and did no studio or touring work as a three-piece. After Coxon significantly thawed on the subject of rejoining Blur, in 2007 band members announced that they would reunite, and that they intended to record together first in August, with the date later being pushed back to September, then October. Though the band members finally met up in October, they posted on their website that they had only "met up for an enjoyable lunch" and that there were no "other music plans for Blur".
