Plain and Fancy: Plain and Fancy is a musical comedy with a book by Joseph Stein and Will Glickman, lyrics by Arnold Horwitt, and music by Albert Hague.  One of the first depictions of an Amish community in American pop culture, it includes a traditional barn raising and an old-fashioned country wedding.

Culture of Bermuda: The culture of Bermuda reflects the heritage of its people, who are chiefly of African and European descent.  A small percentage of Asians also live on the island.  Although Bermuda is an overseas territory of the United Kingdom, it also has strong historical links with the United States.  On one hand, Bermudians seem British in their customs - for example, playing cricket, driving on the left, and having Queen Elizabeth II on their banknotes.  At the same time, a strong North American cultural influence is obvious: the currency is the dollar (on par with the US Dollar); Bermudians frequently watch television from the US; and Bermudian English shares many similarities with American English.  Dress in Bermuda, however, is distinct from either American or British styles.  While in the US or Britain, shorts are considered casual dress, Bermuda shorts are considered to be formal attire in Bermuda, and are worn with a jacket and tie.  Also, despite the island's tropical climate, it is common for Bermudian women to wear heels and stockings while men wear sports jackets and ties both day and night.

Suanfa tongzong: Suanfa tongzong (General Source of Computational Methods) is a mathematical text written by sixteenth century Chinese mathematician Cheng Dawei (1533–1606) and published in the year 1592.  The book contains 595 problems divided into 17 chapters.  The book is essentially general arithmetic for the abacus.  The book was the main source available to scholars concerning mathematics as it developed in China’s tradition.  Six years after the publication of Suanfa Tongzong, Cheng Dawei published another book titled "Suanfa Zuanyao" ("A Compendium of calculating Methods").  About 90% of the content of the new book came from the contents of four chapters of the first book with some rearrangement.  It is said that when Suanfa Tongzong was first published, it sold so many copies that the cost of paper went up and the lucrative sales resulted in unscrupulous people beginning to print pirated copies of the book with many errors.  it was this that forced the author to print an abridged version.

After the group disbanded without releasing any material, Brown made his first appearance on Big L's debut album, "Lifestylez ov da Poor & Dangerous" (1995), on the tracks "8 Iz Enuff" and "Dangerzone".  Eventually, Brown signed a deal with popular hip hop label, Uptown Records and began recording his debut album, "Destined to Be".  In early 1998, the album's lead single "Before We Start" became a minor hit, charting on several "Billboard" charts.  In the Summer of 1998, "Destined to Be" was released but failed to sell many copies, only peaking at 169 on the "Billboard" 200, and Brown was released from his contract.  Brown would make appearances with Heavy D on his album, "Waterbed Hev" and the "Woo" soundtrack.  In 2009, Brown appeared on Mase's mixtape "I Do the Impossible".
