Question: What country of origin does History and Loudon Wainwright Jr. have in common?

Context paragraphs:
Songs in the Dark (album): Songs in the Dark is the debut album by the Wainwright Sisters, a singer-songwriter duo featuring the Canadian-American Martha Wainwright and her American half-sister Lucy Wainwright Roche.  The album, released on November 13, 2015, includes lullabies that their mothers Kate McGarrigle and Suzzy Roche sang to them as children, plus songs by Woody Guthrie, Jimmie Rogers, and their father Loudon Wainwright III.

Older Than My Old Man Now: Older Than My Old Man Now is the twenty-second studio album by American singer-songwriter Loudon Wainwright III, released on April 17, 2012 on 2nd Story Sound Records.  Described as "a gleefully morbid summing up of [Wainwright's] life in which he ponders childhood, family history, aging and death," the album is produced by "" (2009) collaborator Dick Connette, and features contributions from each of Wainwright's children.

Loudon Wainwright Jr.: Loudon Snowden Wainwright Jr. (December 16, 1924 – December 12, 1988) was an American writer.  He was the father of folk singer Loudon Wainwright III and singer Sloan Wainwright, and grandfather to Rufus Wainwright, Martha Wainwright, and Lucy Wainwright Roche.

History (Loudon Wainwright III album): History is the twelfth studio album by American singer-songwriter Loudon Wainwright III, released on September 21, 1992 on Charisma Records.  The album was recorded following the death of Wainwright's father, Loudon Wainwright Jr..  Regarding his father's death and its influence on "History", Wainwright stated that:

Album III: Album III, as its title indicates, is the third full album from Loudon Wainwright III.  It was originally released in 1972 on Columbia Records.  "Album III" would spawn Loudon Wainwright's most popular hit single, "Dead Skunk", one of the many 'novelty songs' sprinkled throughout Wainwright's career.  Although Wainwright has maintained an ironic, sometimes sepulchral sense of humor, "Dead Skunk", despite its commercial success, has dogged him ever since, as he comments on 1985's album "I'm Alright", "Were you embarrassed about 'Dead Skunk'"?

Loudon Wainwright III (album): Loudon Wainwright III (also known as Album I) is the debut album of Loudon Wainwright III.  It was released on vinyl in 1970 on Atlantic Records.  Like his second effort "Album II", the album is a solo acoustic effort.  Though his ironic sense of humour is evident, this is an altogether bleaker and more acerbic album ("Black Uncle Remus", "Four is a Magic Number", "Glad To See You've Got Religion") than most of his 1970s work.

Recovery (Loudon Wainwright album): Recovery is the nineteenth studio album by American singer-songwriter Loudon Wainwright III, released on August 19, 2008 on Yep Roc Records.  The songs are "re-covers" from his first four albums: "Loudon Wainwright III" (1970), "Album II" (1971), "Album III" (1972) and "Attempted Mustache" (1973).

T Shirt (album): T Shirt is a 1976 album by Loudon Wainwright III.  Unlike his earlier records, this (and the subsequent "Final Exam") saw Wainwright adopt a full blown rock band (Slowtrain) - though there are acoustic songs on "T Shirt", including a talking blues.  Nevertheless, it had the misfortune to arrive on the scene at the same time as punk rock, making it immediately dated in the eyes of many critics.  According to Wainwright on the 2006 CD liner notes, it received a scathing review from Rolling Stone Magazine which depressed him so much he stayed in bed for five days.  By the early 1990s, he disowned the album in a radio interview broadcast in Australia.  However, by the time of the CD remaster (which included "Final Exam") he admitted to a much more sympathetic view of the album(s), which he referred to as his 'puppies'.

Last Man on Earth (album): Last Man on Earth is the sixteenth studio album by American singer-songwriter Loudon Wainwright III, released on September 24, 2001 on Red House Records.  Recorded in the wake of Wainwright's mother's death and the collapse of a romantic relationship, the album thematically addresses feelings of grief and loneliness.  In 2012, Wainwright noted, ""Last Man on Earth" was written right after my mother died, so a lot of the material on that record has to do with that momentous event.  The life circle was present on a lot of those songs."

Martha Wainwright: Martha Wainwright (born May 8, 1976) is a Canadian-American folk-rock singer-songwriter.  She is the daughter of American folk singer and actor Loudon Wainwright III and Canadian folk singer-songwriter Kate McGarrigle.  She was raised in a musical family along with her older brother, Rufus Wainwright, in Montreal, Quebec, Canada.
