Question: What documentary had music composed by the person who wrote "I'll Feel a Whole Lot Better"?
Context: "I'll Just Take It Out in Love" is a love song by George Jones.  It rose to #11 when it was released by Epic Records in 1978.  I was written by Bob McDill.  The song, which celebrates domestic tranquility, could not have been more different from what Jones was experiencing in his personal life at the time; the singer was penniless, addicted to alcohol and cocaine, and quickly earning a reputation as the most undependable live performer in show business.  However, despite how much he abused himself, his vocal abilities remained stellar.  In 2006 he explained to "Billboard" magazine, "I would say 90% of the time I would be in pretty damn good shape when I went into the studio.  I did have a little sense, not a whole lot.  But I would still have to have a little build-up of courage, three or four drinks [throughout] the session time.  I don't know, it seemed to mellow you out and relax you a little more, and you would even feel your songs better." The Byrds' Greatest Hits is the first greatest hits album by the American rock band The Byrds and was released in August 1967 on Columbia Records ("see" 1967 in music).  It is the top-selling album in The Byrds' catalogue and reached #6 on the "Billboard" Top LPs chart, but failed to break into the UK Albums Chart.  The album provides a summary of The Byrds' history during Gene Clark and David Crosby's tenure with the band and also functions as a survey of the group's hit singles from 1965 to 1967, a period when the band had its greatest amount of success on the singles chart.  Most of the band's U.S. A-sides from this period are included on the album, along with three of their more important album tracks: "I'll Feel a Whole Lot Better", "The Bells of Rhymney", and "Chimes of Freedom".  The three U.S. singles from this period that are not included on the album are "Set You Free This Time", "Have You Seen Her Face" and "Lady Friend" (although these songs have been included as bonus tracks on various CD reissues of the album).  All of the songs included on the original "Greatest Hits" album can also be found on the band's first four albums, "Mr. Tambourine Man", "Turn!  Turn!  Turn! ", "Fifth Dimension" and "Younger Than Yesterday". "I'll Feel a Whole Lot Better" is a song by the Los Angeles folk rock band The Byrds, first released in June 1965 on the B-side of the band's second single, "All I Really Want to Do".  It was also included on The Byrds' debut album, "Mr. Tambourine Man".  Written by Gene Clark, who also sings the lead vocal, "I'll Feel a Whole Lot Better" features some of The Byrds' early musical trademarks, including Jim McGuinn's jangling 12-string Rickenbacker guitar; Clark's pounding tambourine; McGuinn, Clark, and David Crosby's complex harmony singing; and a country-influenced guitar solo. The Original Singles: 1965–1967, Volume 1 is a compilation album by American rock 'n' roll band The Byrds.  Originally released in 1980, it offered, for the first time, all of the mono single versions of the Byrds' singles released between 1965 and early 1967.  The tracks on the album are laid out chronologically by release date of the single, and features the A-side first, then the B-side.  For example, the Byrds' first single was "Mr. Tambourine Man" with "I Knew I'd Want You" on the B-side.  The next single was "All I Really Want to Do" with "I'll Feel a Whole Lot Better" on the B-side, and so forth. Harold Eugene "Gene" Clark (November 17, 1944 – May 24, 1991) was an American singer-songwriter and founding member of the folk rock band the Byrds.  He was the Byrds' principal songwriter between 1964 and early 1966, writing most of the band's best-known originals from this period, including "I'll Feel a Whole Lot Better", "She Don't Care About Time", and "Set You Free This Time".  Although he did not achieve commercial success as a solo artist, Clark was in the vanguard of popular music during much of his career, prefiguring developments in such disparate subgenres as psychedelic rock, baroque pop, newgrass, country rock, and alternative country. "Falling in Love" is the fourth and final single taken from British pop band McFly's fourth studio album, "".  On 29 April 2009, the song was added to BBC Radio 1's C-List and BBC Radio 2's B-List.  In the UK, "Falling in Love" was released to promote the "" DVD.  In Brazil, the song was released officially on 7 May.  An iTunes bundle, consisting of the Radio Edit and Music Video, was released on 10 May 2009.  The video for the track consists of clips from the group's "" DVD.  The intro has a small resemblance to The Byrds' song "I'll Feel a Whole Lot Better". Marijuana is a 34-minute 1968 anti-drug documentary film by Max Miller and distributed by Avanti Films.  It is narrated by Sonny Bono.  It was described as "the first major film effort to center upon the use and possible risks of marijuana", in which "arguments for and against its use are presented and the accumulation of arguments against is allowed to speak for itself".  Music for the documentary was composed by The Byrds' Gene Clark, a "bizarre" choice in his musical career, resulting in "meandering blues and pseudo-psychedelic instrumental jams". "There's a Whole Lot of Loving" is a 1975 hit song by Guys 'n' Dolls written by Christian Arnold with lyrics by David Martin and Geoff Morrow.  The song was a #2 hit in both the UK and Ireland, and became the biggest hit for the group.  The song was covered as "Whole Lotta Lovin'" by Six and was a number one single in Ireland in 2002. The whole nine yards or the full nine yards is a colloquial American phrase meaning "everything, the whole lot" or, when used as an adjective, "all the way", as in, "The Army came out and gave us the whole nine yards on how they use space systems."  Its origin is unknown and has been described by Yale University librarian Fred R. Shapiro as "the most prominent etymological riddle of our time". My Old, Familiar Friend is the fourth album by American musician Brendan Benson, released August 18, 2009.  The first single, "A Whole Lot Better", was released on the same day.
