Some context: The Twilight Sad are a Scottish post-punk/indie rock band, comprising James Graham (vocals) and Andy MacFarlane (guitar). The band are currently signed to Fat Cat Records and have released four full-length albums, as well as several EPs and singles. Their 2007 debut album, Fourteen Autumns & Fifteen Winters, drew widespread acclaim from critics, who noted Graham's thick Scottish accent and MacFarlane's dense sonic walls of shoegazing guitar and wheezing accordion. The Twilight Sad's notoriously loud live performances have been described as "completely ear-splitting," and the band toured for the album across Europe and the United States throughout 2007 and 2008.
Whilst on tour with Errors in October 2010, vocalist James Graham stated that "the next [album] is not going to be anything like the first two. [...] The wall of sound is kinda gone. Andy [MacFarlane]'s demos involve a lot of keyboards, and it's a lot more considered." Additional musician Martin "Dok" Doherty also stated that "the band who make the same record over and over don't have a very long career." The band returned to the studio in January 2011. In April 2011, the band released a free acoustic EP on their official blog. The release featured stripped-back renditions of tracks from both Forget the Night Ahead and The Wrong Car.  The Twilight Sad's third album, No One Can Ever Know, was released on 6 February 2012. Andy MacFarlane describes the album's sound as "sparser... with a colder, slightly militant feel," and the band received some production assistance from producer Andrew Weatherall, who helped in their experimenting with analog synthesizers. The band released a new song, the album's closing track "Kill It in the Morning", for free on their new website and SoundCloud page on 21 September 2011. The first proper single from the album, "Sick", was made available as a 7" vinyl single and digital download on 14 November 2011. Second single "Another Bed" followed the album's release on 20 February 2012.  In August 2012, the band announced that touring keyboardist Martin "Dok" Doherty would no longer be performing with the band, stating "[An] end of an era as our next two gigs will be Dok's last with the band. One of our best friends and one of the most talented people we know! [...] Been a pleasure and a privilege to share the stage, be on the road [and] have many a drunken night in foreign lands over the past five years with you, Dok." Later that month, Doherty's replacement was revealed to be Brendan Smith, previously of the bands Julia Thirteen and The Unwinding Hours. Regarding the band's line-up changes over the past six years, James Graham noted, "The good thing about the line up changes is that we all remain friends with each other and when someone has left it's been for a good reason and the right choice for them. We've lucked out with Johnny [Docherty] and Brendan who are maniacs in the best possible way, but they are also brilliant musicians as were Dok and Craig [Orzel] and they all put the likes of me to shame." Doherty left the band to further pursue his electropop project Chvrches with former Aereogramme guitarist Iain Cook and singer Lauren Mayberry.  Along with nationwide tours of the United States and the United Kingdom, as well as European festivals during the summer and a headlining gig at Barrowland Ballroom in December, the band released a collection of remixes entitled No One Can Ever Know: The Remixes in November 2012. In December 2013, The Twilight Sad and The Skinny released a free digital download single and video of the band performing "The Wrong Car" with the Royal Scottish National Orchestra, recorded live at Paisley Abbey in October 2013.

Some context: Sir Reginald Carey "Rex" Harrison (5 March 1908 - 2 June 1990) was an English actor of stage and screen. Harrison began his career on the stage in 1924. He served in the Royal Air Force during World War II, reaching the rank of flight lieutenant. He won his first Tony Award for his performance as Henry VIII in the play Anne of the Thousand Days in 1949.
Harrison was born at Derry House in Huyton, Lancashire, the son of Edith Mary (nee Carey) and William Reginald Harrison, a cotton broker. He was educated at Liverpool College. After a bout of childhood measles, Harrison lost most of the sight in his left eye, which on one occasion caused some on-stage difficulty. He first appeared on the stage in 1924 in Liverpool. Harrison's acting career was interrupted during World War II while serving in the Royal Air Force, reaching the rank of Flight Lieutenant. He acted in various stage productions until 11 May 1990. He acted in the West End of London when he was young, appearing in the Terence Rattigan play French Without Tears, which proved to be his breakthrough role.  He alternated appearances in London and New York in such plays as Bell, Book and Candle (1950), Venus Observed, The Cocktail Party, The Kingfisher and The Love of Four Colonels, which he also directed. He won his first Tony Award for his appearance at the Shubert Theatre as Henry VIII in Maxwell Anderson's play Anne of the Thousand Days and international superstardom (and a second Tony) for his portrayal of Henry Higgins in the musical My Fair Lady, where he appeared opposite Julie Andrews.  Later appearances included Pirandello's Henry IV, a 1984 appearance at the Haymarket Theatre with Claudette Colbert in Frederick Lonsdale's Aren't We All?, and one on Broadway at the Brooks Atkinson Theatre presented by Douglas Urbanski, at the Haymarket in J. M. Barrie's The Admirable Crichton with Edward Fox. He returned as Henry Higgins in the revival of My Fair Lady directed by Patrick Garland in 1981, cementing his association with the plays of George Bernard Shaw, which included a Tony nominated performance as Shotover in Heartbreak House, Julius Caesar in Caesar and Cleopatra, and General Burgoyne in a Los Angeles production of The Devil's Disciple.
