Question: Which tour did The Beatles release their album Dark Horse?

<P0-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". <P0-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. <P0-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> <P1-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. <P1-S1>  It is the follow-up to their multi-platinum selling "All the Right Reasons" (2005). <P1-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. <P1-S3>  "Dark Horse" sold 326,000 in its first week and debuted at number 2 in the US. <P1-S4>  More than a year after its release, the album did not leave the Top 100 on the "Billboard" 200. <P1-S5>  In its 91st week, the album peaked at #46 for the week of August 28, 2010. <P1-S6>  From 9 October, the album stayed at #71 for 97 consecutive weeks The album spent 125 consecutive weeks inside the "Billboard" 200. <P1-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> <P2-S0> The Beatles staged their third concert tour of America in August 1966, and it was the last commercial tour they would ever undertake. <P2-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. <P2-S2>  Although it was a commercial success, ticket sales had noticeably declined in number. <P2-S3>  After the tour, they would become a studio band and focused exclusively on record production. <SEP> <P3-S0> "Can't Stop Thinking About You" is a song by English musician George Harrison, released in 1975 on his final album for Apple Records, "Extra Texture (Read All About It)". <P3-S1>  A love song in the style of a soul/R&B ballad, it was written by Harrison in December 1973, towards the end of his marriage to Pattie Boyd and while he was having an affair with Maureen Starkey, the wife of his former Beatles bandmate Ringo Starr. <P3-S2>  Having first considered the song for his 1974 release "Dark Horse", Harrison recorded "Can't Stop Thinking About You" in Los Angeles in May 1975 for his so-called "soul album", "Extra Texture". <P3-S3>  Some authors view its inclusion on the latter release as an obvious attempt by Harrison to commercialise the album, in response to the harsh critical reception afforded "Dark Horse" and his 1974 North American tour.
