You Are My Sunshine is an album by Elizabeth Mitchell released in 2002.
 The album is a collection of children's music played in various styles, including folk, gospel, reggae and rock.
 It features covers of a variety of songs by other artists, among them "Hey Bo Diddley" by Bo Diddley, "Car Car" by Woody Guthrie, Cat Stevens' "Here Comes My Baby" and "Goodnight Irene" by Lead Belly.
"Goodnight, Irene" or "Irene, Goodnight," is a 20th-century American folk standard, written in 3/4 time, first recorded by American blues musician Huddie 'Lead Belly' Ledbetter in 1933.
Huddie William Ledbetter (January 20, 1888 – December 6, 1949) was an American folk and blues musician notable for his strong vocals, virtuosity on the twelve-string guitar, and the folk standards he introduced.
 He is best known as Lead Belly.
 Though many releases credit him as "Leadbelly", he himself wrote it as "Lead Belly", which is also the spelling on his tombstone and the spelling used by the Lead Belly Foundation.
Bobby Singh, is an Australian tabla player.
 He was one of the musician responsible for the album "Djan Djan" which won the 2010 ARIA Award for Best World Music Album.
 Singh is also a member of Rasa Duende.
In music, an electronic tuner is a device that detects and displays the pitch of musical notes played on a musical instrument.
 "Pitch" is the highness or lowness of a musical note, which is typically measured in Hertz.
 Simple tuners indicate—typically with an analog needle-dial, LEDs, or an LCD screen—whether a pitch is lower, higher, or equal to the desired pitch.
 In the 2010s, software applications can turn a smartphone, tablet, or personal computer into a tuner.
 More complex and expensive tuners indicate pitch more precisely.
 Tuners vary in size from units that fit in a pocket to 19" rack-mount units.
 Instrument technicians, piano tuners, and violin-family luthiers typically use more expensive, accurate tuners.
Moses Asch (December 2, 1905 – October 19, 1986), often known as Moe Asch, was a Polish-American recording engineer and record executive.
 He founded Asch Records, which then changed its name to Folkways Records when the label transitioned from 78 RPM recordings to LP records.
 Asch ran the Folkways label from 1948 until his death in 1986.
 Folkways was very influential in bringing folk music into the American cultural mainstream.
 Some of America's greatest folk songs were originally recorded for Asch, including "This Land Is Your Land" by Woody Guthrie and "Goodnight Irene" by Lead Belly.
 Asch sold many commercial recordings to Verve Records; after his death, Asch's archive of ethnic recordings was acquired by the Smithsonian Institution, and released as Smithsonian Folkways Records.
The Penthouse Tapes is the sixth album by The Sensational Alex Harvey Band and is the first one to consist almost entirely of cover songs that range from The Osmonds "Crazy Horses", Alice Cooper's "School's Out", to Lead Belly's "Goodnight Irene".
 It was originally released in 1976 on Vertigo Records.
Vasily Vasilievich Andreyev (Russian: Василий Васильевич Андреев ; 15 January [O.S. 3 January] 1861 1918) was a Russian musician responsible for the modern development of the balalaika and several other traditional Russian folk music instruments, and is considered the father of the academic folk instrument movement in Eastern Europe.
 His accomplishments included:
The Alexander Brothers were an American pop music duo who achieved minor success as Mercury Records artists in the early 1950s.
 Their recording of "Goodnight Irene" charted briefly in September 1950.
 "Goodnight Irene" was recorded in 1950 as part of a four-song session which included the song Mona Lisa which received notice from trade publications.
 Later that year they provided vocals in a session by Mr. Goon-Bones & Barney Lantz.
 Another four-song session for the Alexander Brothers was produced in 1951.
