Question: Courtney Love and Peter Bjorn and John, have which mutual occupation?
Context: Peter Bjorn and John are a Swedish indie pop/rock band, formed in Stockholm in 1999 and named after the first names of the band's members: Peter Morén (vocals, guitar and harmonica), Björn Yttling (bass guitar, keyboards and vocals) and John Eriksson, known in his solo work as Hortlax Cobra (drums, percussion and vocals).  Yttling also worked as producer for the band's first four albums. Peter Bjorn and John is the first album by Swedish indie-pop band Peter Bjorn and John.  Its style takes influences from baroque-pop, post-punk and soul ('From Now On'), and it is colloquially referred to by the band as 'The Red Album'.  Self-titled, it is the only album by the band not to follow their tradition of naming albums with two words, the first with two syllables and the last with one.  However, it does adhere to their rule of always having three of something, if not the band members themselves, on the front cover.  The Wichita Recordings re-release included five bonus tracks from the album's four singles; 'Firing Blanks' & 'Don't Be Skew' from the 'I Don't Know What I Want Us To Do' single, 'Le Crique' from the 'People They Know' single, and 'The Fan' and 'Saturday Night At The Parties' from the '100 M Of Hurdles' EP.  Session musicians appear on some tracks, as the band originally intended to be a quartet.  The album and its singles feature artwork designed by Eric Segol. Courtney Michelle Love (born Courtney Michelle Harrison; July 9, 1964) is an American singer, songwriter, actress, and visual artist.  Prolific in the punk and grunge scenes of the 1990s, Love has enjoyed a career that spans four decades.  She rose to prominence as the frontwoman of the alternative rock band Hole, which she formed in 1989.  Love has drawn public attention for her uninhibited live performances and confrontational lyrics, as well as her highly publicized personal life following her marriage to Kurt Cobain. The Last Tycoon is the debut solo album by Swedish musician Peter Morén of the band Peter Bjorn And John.  The album revolves mainly around the theme of adolescence (the track 'This Is What I Came For' is especially autobiographical), though its title is taken from the unfinished The Last Tycoon by F. Scott Fitzgerald.  Morén's initial plan was to make a purely acoustic record, but the final product contains elements such as string sections and synthesisers.  It was released by V2 Records under license from Wichita Recordings.  The album was recorded "...in our spare, stolen hours, here and there in apartments, rehearsal spaces and studios in Stockholm...".  The album had two singles; Social Competence, released in March, followed by Reel Too Real in April.  The album was produced by songwriter Tobias Fröberg, and Daniel Värjö, member of The Concretes, whose former member Victoria Bergsman Morén had previously collaborated with on the Peter Bjorn And John song Young Folks. "Last Ones Standing" is a song by British recording artist Example.  This is the fourth single from Example's second album, "Won't Go Quietly".  The song was available to download on 12 September 2010, with a physical single release on 13 September 2010.  Production was handled by Bjorn Yttling of Swedish rock band, Peter Bjorn and John. Liv (stylized as "liv") is a Swedish/American supergroup consisting of musicians Lykke Li, Andrew Wyatt and Pontus Winnberg of Miike Snow, Björn Yttling of Peter Bjorn and John, and Jeff Bhasker formed in 2016.  Liv is the Swedish word for "life".  Lykke Li described the band as “the love child of ABBA and Fleetwood Mac.” .  All band members are part of the Swedish artist collective Ingrid, which they spearheaded in 2012. Falling Out is the second album by Peter Bjorn and John, released on October 4, 2004.  While no videos were released, three singles were derived from the album; the promo-only single for Tailormade and full releases for Teen Love and It Beats Me Every Time. Seaside Rock is the fourth album by Peter Bjorn and John.  A vinyl- and digital- only release, it came out in the U.S. on Almost Gold/Star Time International on 23 September 2008.  The U.S. edition is limited to 5000 LPs, each accompanied by a download code.  (V2 released the album in the trio's native Sweden, while Wichita handled it in the UK.) Seaside Rock is an experimental, almost completely instrumental album; aside from some vocals in 'Say Something', the only other vocals appearing on the album are Swedish, spoken word pieces performed over backing music by Peter Bjorn And John read by people in their local community, such as a nearby hairdresser.  The album was included in CD form in the deluxe edition of their 2009 album "Living Thing". "It Don't Move Me" is the a song by Swedish rock band Peter Bjorn and John, released as the third single from their fifth studio album "Living Thing".  It was written and composed by group members Peter Morén, Björn Yttling, and John Eriksson, and produced by the latter of the three.  The song, like much of the album, is influenced by synthpop, featuring common synthpop elements such as electronically tweaked drums and synthesizers. "Nothing to Worry About" is the first single by Peter Bjorn and John from the album "Living Thing".  The music video premiered in 2009.  The song was featured in a season five episode of the MTV series "The Hills" entitled "Crazy In Love".  The song was featured in commercials for the fifth season of "It's Always Sunny in Philadelphia", Cinemax HD in its spring 2009 ad campaign, and EA Sports game, "FIFA 10".  A remix of the song was also used in the promo for season five of the TV series Bones.
