Gamboa is a small town in the Republic of Panama. It was one of a handful of permanent Canal Zone townships, built to house employees of the Panama Canal and their dependents. The name Gamboa is the name of a tree of the quince family.

Gamboa is located on a sharp bend of the Chagres River at the point which feeds Lake Gatun. Just south of Gamboa, Lake Gatun and the Chagres meet the Gaillard Cut where the Canal cuts through the Continental Divide. Thus, though Gamboa is closer to the Pacific side of Panama, its watershed is on the Atlantic side. A single lane iron and wood bridge crosses the Chagres and is the only road access to Gamboa. This bridge is still in use today. Vehicles waiting to pass over the bridge must wait for a stoplight to enter the bridge, since it is only capable of providing space for one lane of traffic at a time. In December 2010 this bridge was the site of massive flooding and huge floating islands passing under the bridge, with trees violently hitting it, which led to the temporary closure of the Panama Canal.

Curtis James Jackson III (born July 6, 1975), better known by his stage name 50 Cent, is an American rapper, entrepreneur, investor, record producer, and actor. He rose to fame with the release of his albums Get Rich or Die Tryin' (2003) and The Massacre (2005). His album Get Rich or Die Tryin' has been certified eight times platinum by the RIAA.

Born in the South Jamaica of Queens, New York City, Jackson began drug dealing at the age of twelve during the 1980s crack epidemic. After leaving drug dealing to pursue a rap career, he was shot at and struck by nine bullets during an incident in 2000. After releasing his album Guess Who's Back? in 2002, Jackson was discovered by rapper Eminem and signed to Interscope Records. With the help of Eminem and Dr. Dre, who produced his first major commercial successes, Jackson became one of the world's highest selling rappers. In 2003, he founded the record label G-Unit Records, which signed several successful rappers such as Young Buck, Lloyd Banks, and Tony Yayo.

Caetano Emanuel Viana Teles Veloso (Portuguese pronunciation: [kaeˈtɐ̃nu emanuˈɛw viˈɐ̃nɐ ˈtɛlis veˈlozu]; born August 7, 1942), better known as Caetano Veloso, is a Brazilian composer, singer, guitarist, writer, and political activist. Veloso first became known for his participation in the Brazilian musical movement Tropicalismo, which encompassed theatre, poetry and music in the 1960s, at the beginning of the Brazilian military dictatorship. He has remained a constant creative influence and best-selling performing artist and composer ever since.

Veloso was born in the city of Santo Amaro da Purificação, in Bahia, a state in the northeastern area of Brazil, but moved to Salvador, the state capital, as a college student in the mid-1960s. Soon after the move, Veloso won a music contest and was signed to his first label. He became one of the founders of Tropicalismo with a group of several other musicians and artists—including his sister Maria Bethânia—in the same period. However the Brazilian government at the time viewed Veloso's music and political action as threatening, and he was arrested, along with fellow musician Gilberto Gil, in 1969. The two eventually were exiled from Brazil, and went to London, where they lived for two years. After he moved back to his home country, in 1972, Veloso once again began recording and performing, becoming popular outside of Brazil in the 1980s and 1990s.
