Question: Dark Horse was realeased after the Beetles became what?

<P0-S0> Dark Horse is the sixth studio album by the Canadian rock band Nickelback, released on November 17, 2008, in Europe and a day later elsewhere. <P0-S1>  It is the follow-up to their multi-platinum selling "All the Right Reasons" (2005). <P0-S2>  It was co-produced by the band and producer and songwriter Robert John "Mutt" Lange, known for working with such acts as Foreigner, AC/DC, Bryan Adams, Def Leppard and Shania Twain. <P0-S3>  "Dark Horse" sold 326,000 in its first week and debuted at number 2 in the US. <P0-S4>  More than a year after its release, the album did not leave the Top 100 on the "Billboard" 200. <P0-S5>  In its 91st week, the album peaked at #46 for the week of August 28, 2010. <P0-S6>  From 9 October, the album stayed at #71 for 97 consecutive weeks The album spent 125 consecutive weeks inside the "Billboard" 200. <P0-S7>  On the week of November 29, 2014, Dark Horse re-entered the "Billboard" 200 at #195, more than six years after the album's release. <SEP> <P1-S0> Dark Horse is the fifth studio album by English musician George Harrison, released on Apple Records in December 1974 as the follow-up to "Living in the Material World". <P1-S1>  Although keenly anticipated on release, "Dark Horse" is associated with the controversial North American tour that Harrison staged with co-headliner Ravi Shankar in November and December that year. <P1-S2>  This was the first US tour by a member of the Beatles since 1966, and the public's nostalgia for the band, together with Harrison contracting laryngitis during rehearsals and choosing to feature Shankar so heavily in the program, resulted in scathing concert reviews from some influential music critics. <SEP> <P2-S0> The Goliath beetles (named after the biblical giant Goliath) are any of the five species in the genus Goliathus. <P2-S1>  Goliath beetles are among the largest insects on Earth, if measured in terms of size, bulk and weight. <P2-S2>  They are members of subfamily Cetoniinae, within the family Scarabaeidae. <P2-S3>  Goliath beetles can be found in many of Africa's tropical forests, where they feed primarily on tree sap and fruit. <P2-S4>  Little appears to be known of the larval cycle in the wild, but in captivity, "Goliathus" beetles have been successfully reared from egg to adult using protein-rich foods such as commercial cat and dog food. <P2-S5>  Goliath beetles measure from 60 – for males and 50 - for females, as adults, and can reach weights of up to 80 - in the larval stage, though the adults are only about half this weight. <P2-S6>  The females range from a dark brown to silky white, but the males are normally brown/white/black or black/white. <SEP> <P3-S0> The Beatles staged their third concert tour of America in August 1966, and it was the last commercial tour they would ever undertake. <P3-S1>  Lasting a total of 19 performances, with 17 shows in American venues and two in Toronto, Ontario, Canada, it was plagued with backlash regarding the controversy of John Lennon's remark about the band being "more popular than Jesus", death threats, and the band's own dissatisfaction with the noise levels and their ability to perform live. <P3-S2>  Although it was a commercial success, ticket sales had noticeably declined in number. <P3-S3>  After the tour, they would become a studio band and focused exclusively on record production.
