Question: Hope for Haiti Now included the studio version of the song produced by whom?
Context: "St. Stephen" is a song by the Grateful Dead, written by Jerry Garcia, Phil Lesh and Robert Hunter and originally released on the 1969 studio album "Aoxomoxoa".  The same year, a live version of the song was released on "Live/Dead", their first concert album.  Unlike the studio version, live versions usually included a section of the song called the "William Tell Bridge", which was used to segue into "The Eleven".  After being played frequently in live concerts from the late 1960s to the early 1970s, the song fell out of regular performance; subsequent live performances of St. Stephen were thus considered a special event by deadheads. Open Fire was the first live album released by American hard rock/heavy metal band Y&T.  It was released in 1985 by A&M Records.  The live material was recorded at various locations earlier in that same year.  All of the tracks are live, with the exception of "Summertime Girls," which is the studio version.  The song would eventually become the band's biggest hit.  The studio version of the song also appeared on the band's next proper studio album, "Down for the Count", which was released in November 1985.  The material used on this album was recorded after the release of their previous album (1984's "In Rock We Trust"), but none of those songs appeared on this album. "Where Are Ü Now" is a song produced by American EDM artists Skrillex and Diplo under their collaborative effort Jack Ü, with vocals from Canadian singer Justin Bieber.  The song was released as the second single from the duo's debut studio album, "Skrillex and Diplo Present Jack Ü" (2015), on their respective labels OWSLA and Mad Decent, and is also included on Bieber's fourth studio album "Purpose" (2015).  It was released simultaneously with the album on February 27, 2015, later sent to mainstream radio on April 21, 2015. "Original Sin" is a song produced, written and arranged by Jim Steinman.  Steinman originally wrote, composed, and produced the song for the album of the same name by the musical team called Pandora's Box.  Taylor Dayne covered the song (singing to a stripped-down version of the backup tracks recorded for Pandora's Box), and it was released as a single on June 26, 1994, and included in the soundtrack to the film "The Shadow". A Ticket for Everyone is a live album by English pop punk band Busted.  It contains twelve tracks recorded during the Manchester leg of their "A Present for Everyone" tour, plus the studio version of "Thunderbirds Are Go!" , which had not previously been included on an album in the United Kingdom.  The album contains live versions of the group's singles, as well as a cover of the 1978 Undertones song "Teenage Kicks" and album track "That Thing You Do".  The European version of the albums omits "She Wants to Be Me", due to contractual issues, and the studio version of "Thunderbirds Are Go!" , as it was previously issued on the 2004 reissue of "A Present for Everyone" in Europe. "Lords of Summer" is a song by heavy metal band Metallica.  The song was released in 2014 as a digital single and a limited edition Black Friday vinyl single containing the studio version and a live version of the song, limited to 4,000 copies.  In 2016, a re-recorded version was listed as a song on the deluxe edition of Metallica's tenth studio album, "Hardwired... to Self-Destruct", clocking in at over a minute shorter in length than the demo and first pass version.  The song was later re-recorded as a bonus track on the third disc of Hardwired... to Self-Destruct. "We Are the World 25 for Haiti" is a charity single recorded by the supergroup Artists for Haiti in 2010.  It is a remake of the 1985 hit song "We Are the World", which was written by American musicians Michael Jackson and Lionel Richie, and was recorded by USA for Africa to benefit famine relief in Africa.  Initially, in late 2009, it had been suggested to Richie and Quincy Jones—producer of the original "We Are the World"—that a re-cut version of the song be re-released under the title "Live 25".  Following the magnitude 7.0 M earthquake in Haiti, which devastated the area and killed thousands of people, it was agreed that the song would be re-recorded by new artists, in the hope that it would reach a new generation and help benefit the people of Haiti. Jesus of Cool is the solo debut album by British singer-songwriter Nick Lowe.  Produced by Lowe, it was released in March 1978 by Radar Records in the UK.  In the United States, the album was retitled Pure Pop for Now People, with Columbia Records replacing "Shake and Pop" with "They Called It Rock" (a Rockpile version of the same song, which had been included as a single-sided bonus 45 in the Radar album), swapping the live version of "Heart of the City" for the studio version that had been released as a single on Stiff Records (the other side of the single, "So It Goes", was included in both versions of the album), and adding "Rollers Show" from a pre-Stiff United Artists maxi-single.  The songs are also in a different order than the UK version.
