"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".
