IN: Darrell Lance Abbott (August 20, 1966 - December 8, 2004), also known as Dimebag Darrell and Diamond Darrell, was an American musician and songwriter who was a co-founder of Pantera alongside his brother Vinnie Paul, and founder of Damageplan. He was considered to be one of the driving forces behind groove metal. Abbott was shot and killed by a gunman while on stage during a performance with Damageplan on December 8, 2004, at the Alrosa Villa in Columbus, Ohio. He ranked No. 92 in Rolling Stone magazine's 100 Greatest Guitarists and No. 1 in the UK magazine Metal Hammer.

Abbott formed Pantera in 1981 with his brother Vinnie Paul on drums. Originally, he called himself Diamond Darrell Lance. The band was influenced with thrash metal acts such as Slayer, Megadeth, Venom, and Metallica as well as traditional metal bands such as Black Sabbath, Iron Maiden, Motorhead, and Judas Priest. Shortly after singer Phil Anselmo joined Pantera, Darrell was invited by Dave Mustaine to join Megadeth. Darrell was willing to join, but on the condition that Mustaine also hire his brother Vinnie on drums. As Mustaine already had a drummer, Chuck Behler, Darrell decided to stay with Pantera. Pantera would go on to become a key formulator of the post-thrash subgenre of "groove" metal. It would not be until nine years after forming that Pantera saw its first piece of commercial success in its 1990 major label debut, Cowboys from Hell. Pantera's "groove" style came to fruition in its breakthrough album Vulgar Display of Power, released on February 25, 1992, which saw the replacement of the power metal falsetto vocals with a hardcore-influenced shouted delivery and heavier guitar sound. On Pantera's 1994 album Far Beyond Driven, Abbott, who'd been listed on all prior albums under the moniker "Diamond Darrell", was listed as "Dimebag Darrell". On the night before Pantera's live appearance at the Monsters of Rock in England's Donington Park, the Abbott brothers got involved in altercations at a local club with journalists from magazines Kerrang! and Raw. Pantera began to suffer from mounting tensions between band members in the mid-1990s, largely due to vocalist Phil Anselmo's rampant drug abuse. In 2001, the group went on hiatus, during which time Anselmo worked on side projects, such as Superjoint Ritual and Down. This caused more friction within the band, as the Abbott brothers kept waiting for Anselmo to become available to work with them again. The frustration with Anselmo led to their decision to disband Pantera in 2003.

IN: Sir Reginald Carey "Rex" Harrison (5 March 1908 - 2 June 1990) was an English actor of stage and screen. Harrison began his career on the stage in 1924. He served in the Royal Air Force during World War II, reaching the rank of flight lieutenant. He won his first Tony Award for his performance as Henry VIII in the play Anne of the Thousand Days in 1949.

Harrison was born at Derry House in Huyton, Lancashire, the son of Edith Mary (nee Carey) and William Reginald Harrison, a cotton broker. He was educated at Liverpool College. After a bout of childhood measles, Harrison lost most of the sight in his left eye, which on one occasion caused some on-stage difficulty. He first appeared on the stage in 1924 in Liverpool. Harrison's acting career was interrupted during World War II while serving in the Royal Air Force, reaching the rank of Flight Lieutenant. He acted in various stage productions until 11 May 1990. He acted in the West End of London when he was young, appearing in the Terence Rattigan play French Without Tears, which proved to be his breakthrough role. He alternated appearances in London and New York in such plays as Bell, Book and Candle (1950), Venus Observed, The Cocktail Party, The Kingfisher and The Love of Four Colonels, which he also directed. He won his first Tony Award for his appearance at the Shubert Theatre as Henry VIII in Maxwell Anderson's play Anne of the Thousand Days and international superstardom (and a second Tony) for his portrayal of Henry Higgins in the musical My Fair Lady, where he appeared opposite Julie Andrews. Later appearances included Pirandello's Henry IV, a 1984 appearance at the Haymarket Theatre with Claudette Colbert in Frederick Lonsdale's Aren't We All?, and one on Broadway at the Brooks Atkinson Theatre presented by Douglas Urbanski, at the Haymarket in J. M. Barrie's The Admirable Crichton with Edward Fox. He returned as Henry Higgins in the revival of My Fair Lady directed by Patrick Garland in 1981, cementing his association with the plays of George Bernard Shaw, which included a Tony nominated performance as Shotover in Heartbreak House, Julius Caesar in Caesar and Cleopatra, and General Burgoyne in a Los Angeles production of The Devil's Disciple.
