Background: David John Matthews was born on January 9, 1967 in Johannesburg, the third of four children of parents John and Valerie Matthews. At the age of two years, Matthews moved with his family to Yorktown Heights in Westchester County, New York, where his father, a physicist, started working for IBM. In 1974, the Matthews family moved to Cambridge, England for a year before returning to New York, where his father died from lung cancer in 1977. Biographer Nevin Martell argues that Dave's father's death may be an impetus for his "carpe diem" lyrics.
Context: Before he was known as a musician, Dave Matthews was an amateur actor, appearing onstage in several productions at Charlottesville's Offstage Theatre and Live Arts theater in the early 1990s; the role for which he is best remembered is as a used car salesman in Offstage Theatre's "Just Say No," directed by John Quinn, co-starring Kylie Suture. He played Will Coleman in the 2003 adaptation of the novel Where the Red Fern Grows. In 2005 he played in Because of Winn-Dixie as Otis, a man who works at a pet store and plays guitar. In 2007, Matthews appeared briefly in the movie I Now Pronounce You Chuck and Larry, where he plays a homosexual salesman. In 2008, he appeared in another Adam Sandler movie, You Don't Mess with the Zohan, as a racist redneck character named James. He also had a significant role in Lake City with Sissy Spacek and Troy Garity, in which he portrays the character "Red." He was also in three 2011 movies, The Other Side with Giovanni Ribisi and Jason Lee, In The Woods, starring Debra Winger and Terrence Howard, and the Adam Sandler/Jennifer Aniston comedy Just Go With It where he played Nicole Kidman's husband.  In 2007, Matthews guest starred in the Fox medical-drama series House in the episode "Half-Wit". He played a piano-playing musical savant who ended up having the two hemispheres of his brain severed from each other in order to recover from his epilepsy, but at the expense of his musical abilities. Dave had a piano double for the complex pieces, but played the simpler pieces himself. In the season one episode of House, "Love Hurts", the song "Some Devil" can be heard playing at the end. In another episode, one of the tracks from Stand Up, "You Might Die Trying" was played in the season five episode, "Not Cancer".  The fifth time Matthews appeared as musical guest on Saturday Night Live in November 2009 (which was also the fourth time the Dave Matthews Band appeared on the show), he made an appearance as Ozzy Osbourne in a skit called "The Mellow Show." Bill Hader impersonated Matthews in the same skit.  Matthews was also a cast member and performer in the popular music documentary, Before the Music Dies.
