"Paul Revere" is a song by American hip hop group Beastie Boys, released as the third single from their debut album "Licensed to Ill" (1986).  It was written by Adam Horovitz, Joseph Simmons, Darryl McDaniels, and Rick Rubin.  It was produced by Rick Rubin and the Beastie Boys.  The song tells a fictional story of how the Beastie Boys met. The story of Foreign Legion began in the bay area in the late nineties where rappers Prozack Turner and Marc Stretch were both pursuing their careers as emcees separately.  The universe brought the two together one fateful afternoon in a run down strip club in a filthy part of town where Stretch was working as the daytime DJ, and Turner working for the company that supplied the strip club with everything from the plastic cups for the “bottomless soda” fountain, to the blue cleaning agent the strippers used to spray down the brass pole between sets.  Sharing a love for hip hop music, the two quickly became friends and soon after, band mates.  The two involved themselves with a Hip Hop organization based in Oakland called Ill Crew Universal, which helped to promote Foreign Legion by pushing their demo, booking shows and getting them on Davey D radio show.  Releasing their first single “Full Time B Boy” on ABB Records in 1999 with DJ Design, the group quickly became popular in the bay area, Los Angeles, New York and overseas due to their on stage presence and high powered live shows, complete with costume changes, theatrics and a cynical brand of humor, not normally found in hip hop circles.  Releasing their first full length “Kidnapper Van” on Insiduous Urban Records in 2000, led to more critical acclaim, a U.S., European and two Australian tours, and being courted by the Beastie Boys Mike D. and his then label, Grand Royal. "Don't Play No Game That I Can't Win" is a song by American hip hop group the Beastie Boys, from their eighth studio album "Hot Sauce Committee Part Two".  Featuring American singer Santigold, the song was released as the fourth single from the album on July 26, 2011.  "Don't Play No Game That I Can't Win" was written and produced by group members Michael "Mike D" Diamond, Adam "MCA" Yauch and Adam "Ad-Rock" Horovitz, with additional writing by Santigold. Ill Communication is the fourth studio album by American hip hop group Beastie Boys.  It was released on May 31, 1994 by Grand Royal Records.  Co-produced by Beastie Boys and Mario C., the album is among the band's most varied releases, drawing from hip hop, punk rock, jazz and funk.  As with their prior release "Check Your Head", this album continues the band's trend away from sampling and towards live instruments.
