Background: Hanson is an American pop rock band from Tulsa, Oklahoma, United States, formed by brothers Isaac (guitar, bass, piano, vocals), Taylor (keyboards, piano, guitar, drums, vocals), and Zac (drums, piano, guitar, vocals). Supporting members include Dimitrius Collins (keyboards, guitar), and Andrew Perusi (bass) who have toured and performed live with the band since 2007. They are best known for the 1997 hit song "MMMBop" from their debut album released through Mercury, Polygram, Middle of Nowhere, which earned three Grammy nominations. Despite the enormous commercial success of Middle of Nowhere, the band suffered from the merger that eliminated their label, Mercury Records .
Context: Middle of Nowhere was released in the US on May 6, 1997, selling 10 million copies worldwide. May 6 was declared 'Hanson Day' in Tulsa by Oklahoma's then-governor Frank Keating. Although 'Hanson Day' was originally intended to be a one-time occurrence, many Hanson fans all over the world still recognize May 6 as Hanson Day every year. Hanson's popularity exploded during the summer of 1997, and Mercury Records released Hanson's first documentary Tulsa, Tokyo, and the Middle of Nowhere and their Christmas album Snowed In in the wake of their success. Hanson also launched MOE (which stood for Middle of Everywhere), a fan club magazine that ran for 12 issues. After numerous unauthorized biographies of each of the brothers were published, Hanson turned to their close friend, Jarrod Gollihare of Admiral Twin, to write their authorized biography. Hanson: The Official Book reached number 9 on the New York Times Best Sellers List (nonfiction) on February 1, 1998. The band was nominated for three Grammy Awards in 1998: Record of the Year, Best New Artist, and Best Pop Performance by a Duo or Group with Vocal. During the summer of 1998, Hanson began a highly successful concert tour, the Albertane Tour. They performed a string of shows throughout stadiums and arenas in the US, targeting young audiences with a playful and energetic style. A live album, titled Live From Albertane, was released the following fall, as well as their second documentary The Road to Albertane.  In response to the demand for their earlier work, Hanson re-released MMMBop as 3 Car Garage, minus four tracks, in May 1998. To date, the tracks from Boomerang have not been re-released. Three tracks from Boomerang ("Boomerang", "More Than Anything", and "Rain (Falling Down)") and two of the remaining tracks from MMMBop ("Incredible" and "Baby (You're So Fine)") were released on the first MOE CD sent to fan club members.  During the Albertane Tour, Hanson wrote and demoed what would later become the songs for their second major studio album, This Time Around. During this time period, Mercury Records, the band's label, had been merged with Island Def Jam. Almost immediately following the changeover in May 2000, Hanson released their second album, This Time Around, but due to lack of promotional funding, sales were low and the label eventually pulled funding for their tour. The band toured through the summer and fall of 2000 on their own funds.
Question: what happened on Hanson Day?
Answer: originally intended to be a one-time occurrence, many Hanson fans all over the world still recognize May 6 as Hanson Day every year.

Background: Celtic art is associated with the peoples known as Celts; those who spoke the Celtic languages in Europe from pre-history through to the modern period, as well as the art of ancient peoples whose language is uncertain, but have cultural and stylistic similarities with speakers of Celtic languages. Celtic art is a difficult term to define, covering a huge expanse of time, geography and cultures. A case has been made for artistic continuity in Europe from the Bronze Age, and indeed the preceding Neolithic age; however archaeologists generally use "Celtic" to refer to the culture of the European Iron Age from around 1000 BC onwards, until the conquest by the Roman Empire of most of the territory concerned, and art historians typically begin to talk about "Celtic art" only from the La Tene period (broadly 5th to 1st centuries BC) onwards. Early Celtic art is another term used for this period, stretching in Britain to about 150 AD.
Context: The ancient peoples now called "Celts" spoke a group of languages that had a common origin in the Indo-European language known as Common Celtic or Proto-Celtic. This shared linguistic origin was once widely accepted by scholars to indicate peoples with a common genetic origin in southwest Europe, who had spread their culture by emigration and invasion. Archaeologists identified various cultural traits of these peoples, including styles of art, and traced the culture to the earlier Hallstatt culture and La Tene culture. More recent genetic studies have indicated that various Celtic groups do not all have shared ancestry, and have suggested a diffusion and spread of the culture without necessarily involving significant movement of peoples. The extent to which "Celtic" language, culture and genetics coincided and interacted during prehistoric periods remains very uncertain and controversial.  Celtic art is associated with the peoples known as Celts; those who spoke the Celtic languages in Europe from pre-history through to the modern period, as well as the art of ancient peoples whose language is uncertain, but have cultural and stylistic similarities with speakers of Celtic languages.  The term "Celt" was used in classical times as a synonym for the Gauls (Keltoi, Celtae). Its English form is modern, attested from 1607. In the late 17th century the work of scholars such as Edward Lhuyd brought academic attention to the historic links between Gaulish and the Brythonic--and Goidelic--speaking peoples, from which point the term was applied not just to continental Celts but those in Britain and Ireland. Then in the 18th century the interest in "primitivism", which led to the idea of the "noble savage", brought a wave of enthusiasm for all things Celtic and Druidic. The "Irish revival" came after the Catholic Emancipation Act of 1829 as a conscious attempt to demonstrate an Irish national identity, and with its counterpart in other countries subsequently became the "Celtic Revival".
