Context paragraphs:
Opel (album): Opel is a 1988 album compiled from recordings made by former Pink Floyd frontman Syd Barrett between 1968 and 1970.  The album is a compilation of unreleased material and alternate takes of recordings from sessions for Barrett's solo albums, "The Madcap Laughs" and "Barrett".  Before they were vetoed by Pink Floyd, the album was to include two unreleased tracks that Barrett had worked on while with Pink Floyd, "Scream Thy Last Scream" and "Vegetable Man".

The Madcap Laughs: The Madcap Laughs is the debut solo album by the English singer-songwriter Syd Barrett.  It was recorded after Barrett had left Pink Floyd in April 1968.  The album had a chequered recording history, with work beginning in mid-1968, but the bulk of the sessions taking place between April and July 1969, for which five different producers were credited − including Barrett, Peter Jenner (1968 sessions), Malcolm Jones (early-to-mid-1969 sessions), and fellow Pink Floyd members David Gilmour and Roger Waters (mid-1969 sessions).  Among the guest musicians are Willie Wilson from (Gilmour's old band) Jokers Wild and Robert Wyatt of the band Soft Machine.

Beyond the Wildwood: Beyond the Wildwood – A Tribute to Syd Barrett is a tribute album consisting of music written by Pink Floyd's original guitarist, vocalist and primary songwriter Syd Barrett.  The musicians performing on the album are British and American indie rock artists.  The songs featured come from Pink Floyd's singles; the albums "The Piper at the Gates of Dawn" and "A Saucerful of Secrets"; and Barrett's two solo albums: "The Madcap Laughs" and "Barrett".  Although Barrett's productive recording career had only lasted from 1967 though 1970, his music had a great influence on the development of psychedelic rock, alternative rock and indie rock music.

The Final Cut (album): The Final Cut is the twelfth studio album by the English progressive rock band Pink Floyd, released on 21 March 1983 by Harvest Records in the United Kingdom and on 2 April by Columbia Records in the United States.  It was Pink Floyd's last studio album to include founding member, bass guitarist and songwriter Roger Waters, and their only album on which he alone is credited for writing and composition.  It was also the only Pink Floyd album that does not feature keyboardist Richard Wright.  Waters originally planned "The Final Cut" as a soundtrack album for the 1982 film "Pink Floyd – The Wall".  With the onset of the Falklands War, he rewrote it as a concept album, exploring what he considered the betrayal of his father, who died serving in the Second World War.  Waters sings most of the lyrics; lead guitarist David Gilmour provides lead vocals on only one track.  The packaging, also designed by Waters, reflects the album's war theme.

Barrett was excluded from Pink Floyd in April 1968 after David Gilmour took over as their new guitarist, and was briefly hospitalised amid speculation of mental illness.

The song's arrangement is sparse, like much of the album, and features only acoustic and electric guitar accompaniment to the vocals.  This song, along with "Maisie" and "Bob Dylan Blues"; reflected Barrett's early interest in the blues.  Iggy the Eskimo, one of Barrett's acquaintances, had called the song "quite catchy".
