John Murice Jackson (born June 1, 1950 in Baton Rouge, Louisiana) is an American actor, best known for playing Rear Admiral A. J. Chegwidden on the CBS series JAG.

John was forced to use his middle initial "M." for his professional name because there was already a "John Jackson" registered with the Screen Actors Guild when he joined the union. SAG rules prohibit two or more members from using the same name. (Another actor by the name of John E. Jackson is sometimes confused with John M. Jackson; both use middle initials for the same reason.)

Before JAG, Jackson played as a JAG Officer in A Few Good Men in 1992 as Capt. West.

Jackson played Rear Admiral Albert Jethro 'A.J.' Chegwidden, Judge Advocate General of the United States Navy.

He had a recurring role as FBI Deputy Director Sam Cullen in the first season of Fox series Bones. He appeared in the series finale of Jericho as the ambassador of Texas to the Allied States of America. He portrayed a C-130 pilot Gus in the NBC series Knight Rider and has recently appeared on CSI: Crime Scene Investigation.

John Clayton Mayer ( /ˈmeɪ.ər/ MAY-ər; (born October 16, 1977) is an American pop and blues rock musician, singer-songwriter, recording artist, and music producer. Born in Bridgeport, Connecticut and raised in Fairfield, Connecticut, he attended Berklee College of Music in Boston. He moved to Atlanta in 1997, where he refined his skills and gained a following, and he now lives in New York City. His first two studio albums, Room for Squares and Heavier Things, did well commercially, achieving multi-platinum status. In 2003, he won a Grammy Award for Best Male Pop Vocal Performance for "Your Body Is a Wonderland."

Mayer began his career performing mainly acoustic rock, but gradually began a transition towards the blues genre in 2005 by collaborating with renowned blues artists such as B. B. King, Buddy Guy, and Eric Clapton, and by forming the John Mayer Trio. The blues influence can be heard throughout his 2005 live album Try! with the John Mayer Trio and his third studio album Continuum, released in September 2006. At the 49th Annual Grammy Awards in 2007 Mayer won Best Pop Vocal Album for Continuum and Best Male Pop Vocal Performance for "Waiting on the World to Change".

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
