"Broken Arrow" is a song written by Canadian singer-songwriter Neil Young and recorded by Buffalo Springfield on their 1967 album "Buffalo Springfield Again".
 It was recorded in August and September 1967 at Columbia Recording Studios and Sunset Sound Recorders.
 It incorporates musical ideas from "Down Down Down," a demo Young recorded with Buffalo Springfield (now available on the box set).
King Midas in Reverse is a song by British pop group The Hollies written solely by Graham Nash but credited to Clarke, Nash and Hicks for publishing.
 It was released by The Hollies as single in September 1967 in anticipation of their album "Butterfly".
 The track was a departure in style and was heavily influenced by Graham Nash's visits to the U.S.A. Nash wanted to take the band in a new direction which was resisted by other members of the band, and this led to his departure and move to the U.S.A.
 It was released in the UK on the Parlophone label (R5637) and in the US on the Epic label (10234).
 While a critical success, the song was a commercial failure by the Hollies' standards prompting them to write and record the more commercial song "Jennifer Eccles" for their next single.
Buffalo Springfield is a compilation album released on Atco Records in 1973.
 It is the fifth album by rock band Buffalo Springfield, and their second compilation.
 It was assembled by the label well after the band had broken up at a time when Crosby, Stills, Nash & Young were both quite popular and had not released any new material as a group for over two years, with their 1974 reunion tour eight months away.
 It features a nine-minute extended version of the song "Bluebird" by Stephen Stills (consisting of a live jam appended to the studio version), only available elsewhere on the Warner Special Products LP compilation "Heavy Metal – 24 Electrifying Performances" (Volume 2 in the "Superstars of the 70's" series), released in 1974.
 It has never been issued on compact disc in North America and is currently out of print.
Buffalo Springfield is a career retrospective album by the 1960s folk rock band of the same name, released in 2001.
 Band member Neil Young assembled the tracks in chronological order to show how the band evolved and disintegrated in the span of two years.
 Of the four CDs, the first three represent the actual box set while the fourth CD contains the band's first two albums, all but two tracks of which had already appeared in identical versions elsewhere on the first three CDs.
 It reached #194 on Billboard's Top 200 Album chart, and stayed on the chart for the single week.
 The set omits the stereo version of the "Buffalo Springfield" album, the mono version of "Buffalo Springfield Again", the album versions of "On The Way Home", "Pretty Girl Why", and "Four Days Gone" from "Last Time Around", and the songs "Carefree Country Day" and "In The Hour Of Not Quite Rain" from "Last Time Around".
 It also lacks the long version of "Bluebird", only ever issued on the band's self-titled 2-LP compilation, "Buffalo Springfield," released in 1973.
Crosby, Stills & Nash (CSN) was a vocal folk rock supergroup made up of American singer-songwriters David Crosby and Stephen Stills and English singer-songwriter Graham Nash.
 They were known as Crosby, Stills, Nash & Young (CSNY) when joined by Canadian singer-songwriter Neil Young, who was an occasional fourth member.
 They were noted for their intricate vocal harmonies, often tumultuous interpersonal relationships, political activism, and lasting influence on US music and culture.
 Crosby, Stills & Nash were inducted into the Rock and Roll Hall of Fame and all three members were also inducted for their work in other groups (Crosby for the Byrds, Stills for Buffalo Springfield and Nash for the Hollies).
 Neil Young has also been inducted as a solo artist and as a member of Buffalo Springfield.
Paul Richard "Richie" Furay (born May 9, 1944) is an American singer, songwriter, and Rock & Roll Hall of Fame member who is best known for forming the bands Buffalo Springfield with Stephen Stills, Neil Young, Bruce Palmer, and Dewey Martin, and Poco with Jim Messina, Rusty Young, George Grantham and Randy Meisner.
 His best known song (originally written during his tenure in Buffalo Springfield, but eventually performed by Poco, as well) was "Kind Woman", which he wrote for his wife, Nancy.
"Immigration Man" is a song written by Graham Nash and recorded by David Crosby and Graham Nash, released as a single in March 1972.
 It was the lead single for the duo's debut album, "Graham Nash David Crosby".
 It peaked at #36 on the "Billboard" Hot 100, and is their only Top 40 hit as a duo.
"War Song" is a 1972 single credited to Neil Young & Graham Nash, backed by The Stray Gators.
 It was released in support of George McGovern's 1972 presidential campaign, who was running against incumbent President Richard Nixon.
 Young had already voiced his opinions of Nixon two years prior with "Ohio" while a member of Crosby, Stills & Nash, and once again tried to make an impact with a protest song.
 Despite his and Nash's intentions, the single failed to make a serious impression.
"Expecting to Fly" is a song written by Neil Young and performed by Buffalo Springfield.
 The song reached #98 on the "Billboard" Hot 100 in 1968.
 The song appeared on their 1967 album, "Buffalo Springfield Again".
 Producer Jack Nitzsche provided the orchestral arrangement featuring a string section plus an oboe.
 Nitzsche had also worked with the Buffalo Springfield song "On the Way Home", and "Broken Arrow", both written by Neil Young.
 Live versions from Young's early solo performances appear on the albums "Live at the Riverboat 1969", "Sugar Mountain – Live at Canterbury House 1968", and "Live at the Cellar Door".
Neil Percival Young, {'1': ", '2': ", '3': ", '4': "} (born November 12, 1945), is a Canadian singer-songwriter, musician, producer, director and screenwriter.
 After embarking on a music career in the 1960s, he moved to Los Angeles, where he formed Buffalo Springfield with Stephen Stills, Richie Furay and others.
 Young had released two solo albums by the time he joined Crosby, Stills & Nash in 1969, in addition to two as a member of Buffalo Springfield.
 From his early solo albums and those with his backing band Crazy Horse, Young has recorded a steady stream of studio and live albums, sometimes warring with his recording company along the way.
