The Bee Gees were a pop music group formed in 1958. Their lineup consisted of brothers Barry, Robin, and Maurice Gibb. The trio were successful for most of their decades of recording music, but they had two distinct periods of exceptional success: as a popular music act in the late 1960s and early 1970s, and as prominent performers of the disco music era in the mid-to-late 1970s. The group sang recognisable three-part tight harmonies; Robin's clear vibrato lead vocals were a hallmark of their earlier hits, while Barry's R&B falsetto became their signature sound during the mid-to-late 1970s and 1980s.

In an interview with Easy Mix radio host Tim Roxborough on 1 September 2009, Barry's 63rd birthday, Barry commented on future tours saying that "they will be back"; but in an agreement with Warner/Rhino they would not make an announcement at that time. On 7 September 2009, Robin disclosed to Jonathan Agnew that he had been in touch with Barry and that they had agreed that the Bee Gees would re-form and "perform again".  Barry and Robin performed on the BBC's Strictly Come Dancing on 31 October 2009 and appeared on ABC-TV's Dancing with the Stars on 17 November 2009. On 15 March 2010, Barry and Robin inducted the Swedish group ABBA into the Rock and Roll Hall of Fame. On 26 May 2010, the two made a surprise appearance on the ninth-season finale of American Idol.  On 20 November 2011 it was announced that Robin Gibb, at 61 years old, had been diagnosed with liver cancer, a condition he had become aware of several months earlier. He had become noticeably thinner in previous months and had to cancel several appearances due to issues with severe abdominal pain.  On 13 February 2012, Robin joined British military trio the Soldiers for the Coming Home charity concert at the London Palladium, in support of injured servicemen. It was his first public appearance for almost five months and his final.  On 14 April 2012, it was reported that Robin had contracted pneumonia in a Chelsea hospital and was in a coma. Although he came out of his coma on 20 April 2012, his condition deteriorated rapidly, and he died on 20 May 2012 of liver and kidney failure. With Robin's death, Barry became the last surviving Gibb brother, and the Bee Gees dissolved as a musical group. CANNOTANSWERAnswer this question using a quote from the following article:

The Bee Gees var en popmusikgrupp bildad 1958. Deras sättning bestod av bröderna Barry, Robin och Maurice Gibb. Trion var framgångsrik under större delen av sina decennier av inspelning av musik, men de hade två distinkta perioder av exceptionella framgångar: som populärmusikakt i slutet av 1960-talet och början av 1970-talet, och som framstående artister av discomusikepoken i mitten till slutet av 1970-talet. Gruppen sjöng igenkännliga tredelade strama harmonier; Robins tydliga vibrato leadsång var ett kännetecken för deras tidigare hits, medan Barrys R&B falsetto blev deras signatursound under mitten till slutet av 1970- och 1980-talet. I en intervju med Easy Mix radioprogramledare Tim Roxborough den 1 september 2009 kommenterade Barrys 63:e födelsedag, Barry kommande turnéer som säger att "de kommer att vara tillbaka"; men i ett avtal med Warner/Rhino skulle de inte göra något tillkännagivande vid den tiden. Den 7 september 2009 avslöjade Robin för Jonathan Agnew att han hade varit i kontakt med Barry och att de hade kommit överens om att Bee Gees skulle omforma och "uppträda igen". Barry och Robin uppträdde på BBC:s Strictly Come Dancing den 31 oktober 2009 och medverkade på ABC-TV:s Dancing with the Stars den 17 november 2009. Den 15 mars 2010 inledde Barry och Robin den svenska gruppen ABBA in i Rock and Roll Hall of Fame. Den 26 maj 2010 gjorde de två ett överraskande framträdande på nionde säsongens final av American Idol. Den 20 november 2011 meddelades det att Robin Gibb, vid 61 års ålder, hade fått diagnosen levercancer, ett tillstånd han hade blivit medveten om flera månader tidigare. Han hade blivit märkbart tunnare under tidigare månader och fick ställa in flera framträdanden på grund av problem med svår buksmärtor. Den 13 februari 2012 anslöt Robin till brittiska militärtrion Soldaterna för välgörenhetskonserten Coming Home på London Palladium, till stöd för skadade servicemän. Det var hans första offentliga framträdande på nästan fem månader och hans final. Den 14 april 2012 rapporterades det att Robin hade ådragit sig lunginflammation på ett Chelsea-sjukhus och låg i koma. Trots att han kom ur sin koma den 20 april 2012 försämrades hans tillstånd snabbt, och han avled den 20 maj 2012 av lever- och njursvikt. I och med Robins död blev Barry den sista överlevande Gibb-brodern, och Bee Gees upplöstes som en musikalisk grupp. CANNOTANSWERAnswer denna fråga med hjälp av ett citat från följande artikel: Vad hände 2011?
