The band currently consists of James Graham (vocals), Andy MacFarlane (guitar, producer), and Mark Devine (drums).  The Kilsyth-based band formed in 2003 and were signed to Fat Cat Records when Alex Knight, co-founder of the label, went to Glasgow to watch the band perform their third gig and signed them on the spot.  The band released their debut EP "The Twilight Sad" in November 2006 in the United States only, followed by their debut album "Fourteen Autumns & Fifteen Winters" in April 2007, which garnered widespread critical acclaim.  The album spawned two singles, "That Summer, at Home I Had Become the Invisible Boy" in April, and "And She Would Darken the Memory" in July.  The following year, the band released "Here, It Never Snowed.  Afterwards It Did", a mini-album of reworked versions of songs from "Fourteen Autumns & Fifteen Winters" and two non-album tracks, inspired by stripped-down live performances.  A collection of live versions and previously unreleased tracks entitled "Killed My Parents and Hit the Road" was released in December 2008.  The Twilight Sad's second studio album, "Forget the Night Ahead", was released in September 2009 to further acclaim and marked a shift in the band's direction towards a darker and more streamlined sound.

Nunca Voy a Olvidarte: "Nunca Voy a Olvidarte" (English: "I Am Never Going to Forget You") is a song written by Roberto Belester and first recorded by Mexican norteño band Bronco for their album "Salvaje y Tierno" (1991).  In the song, the protagonist is leaving and vows to never forget the time he spent with his lover.

Castro's version peaked at number-one on the "Billboard" Hot Latin Songs chart in the United States became his first number-one single.

The Entertainer (song): "The Entertainer" is a single by singer Billy Joel released as the only single from his 1974 album "Streetlife Serenade".  The song peaked at #34 on the US charts, a Top 40 hit for Joel that year.  The song is a cynical and somewhat satirical look at the fleeting fame of a musician and fickle public tastes ("Today I am your champion / I may have won your hearts / But I know the game / You'll forget my name / And I won't be here / in another year / if I don't stay on the charts"); this theme would be examined in the later song "It's Still Rock and Roll to Me".  Another verse in the song references the shortening of Joel's song, "Piano Man", from 5 minutes and 38 seconds to 3 minutes and 5 seconds to fit a radio slot, referenced by the lyrics "It was a beautiful song, / but it ran too long / If you're gonna have a hit, you gotta make it fit / So they cut it down to 3:05."  Additionally, the timing printed on the label of the 7" release of "The Entertainer" was 3:05, although the actual 45 length was 3:11 (while the album length was 3:41).  In the single version, Verse 3 (which starts at 1:02 in the album version) is edited out, and Verse 2 (which starts at 0:40) contains a steel guitar in its second half, which is actually featured in the second half of the "third" verse in the album version; indeed, on the single mix, the instrumental crescendo of the album version is anticipated by bringing the fuller instrumentation of Verse 3 under the vocals of Verse 2.  As a result of this, the slightly emptier original instrumentation of Verse 2 (which includes a downward slide on the synth) and the vocals of Verse 3 are completely omitted, while the instrumentation of Verse 3 (featuring the steel guitar) does appear, but earlier.

Open Your Eyes (Warzone album): Open Your Eyes was the second full-length album from New York hardcore band, Warzone – who originated in Lower East Side, Manhattan, United States.

Witchcraft (Witchcraft album): Witchcraft is the debut album from the Swedish doom metal band Witchcraft.  The album was released in 2004 by Rise Above Records.  "Please Don't Forget Me" and "Yes I Do" are both covers of 70s-era Pentagram.  "Yes I Do" appears on the original LP version and the Japanese press; it does not appear on the picture disc.  "Please Don't Forget Me" is credited to Bobbly Liebling on the sleeve and is often mis-accredited to Liebling's pre-Pentagram outfit, Stone Bunny.  The cover image is a slightly altered version of a print called "Merlin", a pen-and-ink drawing by Aubrey Beardsley for an 1893-94 edition of Sir Thomas Malory's "Le Morte d'Arthur".  Additionally, the band formed to be a one-off tribute band to both Bobby Liebling and Roky Erickson, and only intended to make one song (No Angel or Demon) however, they continued and are now an original band.
