Question: The Billy Preston album "Encouraging Words" was released in 1970 on a record label founded by what group? 

Context paragraphs:
All Things Must Pass (song): "All Things Must Pass" is a song by English musician George Harrison, issued in November 1970 as the title track to his triple album of the same name.  Billy Preston released the song originally – as "All Things (Must) Pass" – on his Apple Records album "Encouraging Words" (1970), after the Beatles had rejected it for inclusion on their "Let It Be" album in January 1969.  The composition reflects the influence of the Band's sound and communal music-making on Harrison, after he had spent time with the group in Woodstock, New York, in late 1968, while Timothy Leary's poem "All Things Pass", a psychedelic adaptation of the Tao Te Ching, provided inspiration for his song lyrics.

That's the Way God Planned It (song): "That's the Way God Planned It" is a song by American musician Billy Preston and the title track to his 1969 album of the same name.  Issued as a single, the song was Preston's first release on the Beatles' Apple record label, following his guest role on the band's "Get Back" single.  The lyrics to "That's the Way God Planned It" partly reflect the long musical apprenticeship Preston had served since childhood, mentored by artists such as Sam Cooke and Ray Charles,<ref name="Robins/Creem">Wayne Robins, "Billy Preston", "Creem", May 1974; available at Rock's Backpages ("subscription required"). </ref> while musically the track combines the gospel tradition with rock.  Produced by George Harrison in London, the recording also features contributions from Eric Clapton, Keith Richards, Ginger Baker and Doris Troy.  Having been edited down to three minutes for its single release, the full version appeared on the album, as "That's the Way God Planned It (Parts 1 & 2)".

Vanity label: A vanity label (see related topic on vanity press) is an informal name given sometimes to a record label founded as a wholly or partially owned subsidiary of another, larger and better established (at least at the time of the vanity label's founding) record label, where the subsidiary label is (at least nominally) controlled by a successful recording artist, designed to allow this artist to release music by other artists they admire.  The parent label handles the production and distribution and funding of the vanity label, but the album is usually released with the vanity label brand name prominent.  Usually, the artist/head of the vanity label is signed to the parent label, and this artist's own recordings will be released under the vanity label's brand name.  Creating a vanity label can be an attractive idea for the parent label primarily as a "perk" to keep a successful artist on the label's roster happy and a venue to bring fellow artists to the public's attention.

Apple Records: Apple Records is a record label founded by the Beatles in 1968, as a division of Apple Corps Ltd.  It was initially intended as a creative outlet for the Beatles, both as a group and individually, plus a selection of other artists including Mary Hopkin, James Taylor, Badfinger, and Billy Preston.  In practice, by the mid-1970s, the roster had become dominated with releases by the former Beatles as solo artists.  Allen Klein managed the label from 1969 to 1973.  It was then managed by Neil Aspinall on behalf of the four Beatles and their heirs.  He retired in 2007 and was replaced by Jeff Jones.

Encouraging Words: Encouraging Words is the fifth studio album by Billy Preston, released in 1970 on Apple Records.  It was the second and last of his albums for the Beatles' label, after which he moved to A&M.

Black Sheep (rock band): Black Sheep, a Rochester, New York-based 1970s United States rock music band, was one of vocalist Lou Gramm's early working bands (it followed Poor Heart, which broke up c. 1970).  The group, which had released the single "Stick Around" in 1974, the album "Black Sheep" in 1975, and the album "Encouraging Words" in late 1975, was no longer performing when Gramm was invited by Mick Jones to join the band Foreigner in 1976.

My Sweet Lord: "My Sweet Lord" is a song by English musician and Beatle, George Harrison.  It was released in November 1970 on his triple album "All Things Must Pass".  Also issued as a single, Harrison's first as a solo artist, "My Sweet Lord" topped charts worldwide and was the biggest-selling single of 1971 in the UK.  In America and Britain, the song was the first number-one single by an ex-Beatle.  Harrison originally gave the song to his fellow Apple Records artist Billy Preston to record; this version, which Harrison co-produced, appeared on Preston's "Encouraging Words" album in September 1970.

Mavin Records: Mavin Records (also known as the Supreme Mavin Dynasty) is a revamped Nigerian-based record label founded by recording artist and record producer Don Jazzy on May 8, 2012.  The label's inception came to fruition following the closure of Mo' Hits Records, a record label owned by the aforementioned producer and D'banj.  The label is home to recording artists such as Tiwa Savage, Iyanya, Dr SID, D'Prince, Di'Ja, Reekado Banks, Korede Bello, Johnny Drille, Poe, and the DNA Twins.  The label also houses a roster of producers such as Jazzy himself, Altims and Baby Fresh.  In 2014, DJ Big N became the label's official disc jockey.  Wande Coal was formerly signed to the label.  On May 8, 2012, the label released a compilation album titled "Solar Plexus".

Come and Get It: The Best of Apple Records: Come and Get It: The Best of Apple Records is a greatest hits compilation album containing songs by artists signed to the Beatles' Apple record label between 1968 and 1973.  The first such multi-artist Apple compilation, it was released on 25 October 2010.  Among the artists are Badfinger, Mary Hopkin, James Taylor, Billy Preston, Jackie Lomax, Ronnie Spector and Hot Chocolate.  In most cases, the recordings were produced by one of the Beatles, with George Harrison and Paul McCartney being the most heavily represented on the album.

Apple Records discography: This is the discography of Apple Records, a record label formed by the Beatles in 1968.  During its early years, the label enjoyed a fair degree of commercial success, most notably with Mary Hopkin and Badfinger, as well as discovering acts such as James Taylor and Billy Preston who would go on to greater success with other labels.  However, by the mid-1970s, Apple had become little more than an outlet for the Beatles' solo recordings (although, as the solo Beatles were actually still under contract to EMI, the Apple label was, in truth, only a cosmetic addition to their releases).  After EMI's contract with the Beatles ended in 1976, the Apple label was finally wound up.  The label was reactivated in the 1990s with many of the original Apple albums being reissued on compact disc, and the company now oversees new Beatles releases such as the "Anthology" and "1" albums as well as the 2009 Beatles remastering programme.  In 2010, Apple set about remastering and reissuing its back catalogue for a second time.
