Problem: Background: Michael Anthony Orlando Cassavitis (born April 3, 1944), known professionally as Tony Orlando, is an American singer, songwriter, producer, music executive, and actor, best known as the lead singer of the group Tony Orlando and Dawn in the 1970s. Orlando formed the doowop group The Five Gents in 1959 at the age of 15, with whom he recorded demos, and got the attention of music publisher and producer Don Kirshner. Kirshner hired him to songwrite at 1650 Broadway, Manhattan as part New York's thriving Brill Building songwriting community, along with other songwriters Carole King, Neil Sedaka, Toni Wine, Barry Mann, Cynthia Weil, Bobby Darin, Connie Francis, and Tom and Jerry, who didn't make it in the office until they later changed their name to Simon and Garfunkel. Orlando was also hired to sing on songwriter demos, and singles released with Orlando as a solo artist began to hit the charts in the US and the UK beginning in 1961 with "Halfway to Paradise" and "Bless You" when he was 16.
Context: Orlando was tempted back to a recording career when he was asked to record a demo record of "Candida", with backup singers including Toni Wine (who wrote the song) and Linda November. Concerned about a possible conflict of interest with his April-Blackwood duties, Orlando sang under the condition that his name not be associated with the project, so it was released under the simple name of "Dawn", the middle name of the daughter of Bell records executive Steve Wax. The song became a hit, and Dawn, with Wine and November again singing backup, recorded another song, "Knock Three Times", which itself became a #1 hit. Orlando then wanted to go on tour, and asked two other session singers, Telma Hopkins and Joyce Vincent Wilson to join for the tour. Orlando then discovered that there were six touring groups using that name, so Dawn became "Dawn featuring Tony Orlando", which changed to Tony Orlando and Dawn in 1973. The new group recorded more hits, including "Tie a Yellow Ribbon Round the Ole Oak Tree" (1973) and "He Don't Love You (Like I Love You)" (1975), a cover of the Jerry Butler hit, "He Will Break Your Heart". With a successful recording career, Orlando then set his sights on television. As described in The San Francisco Chronicle, "Tony Orlando and Dawn burst out of television sets during the Ford administration, a sunny antidote to the dark cynicism that followed Watergate. He represented simple, traditional values, a conservative return to pure entertainment. He drew a happy face in the "O" of his autograph. It was not terribly cool, but America loved him." The Tony Orlando and Dawn Show on CBS became a hit, a summer replacement for the Sonny & Cher show, and ran for four seasons from 1973 to 1976. It welcomed the biggest names in show business each week as Orlando's guests, including his boyhood idols, Jackie Gleason and Jerry Lewis. At the 1976 Republican National Convention in Kansas City, Missouri, Orlando danced to the tune of "Tie a Yellow Ribbon" with then First Lady Betty Ford. The media stated that it was to divert attention as Nancy Reagan entered the Kemper Arena convention hall. However, in Orlando's book Halfway to Paradise, he states that Mrs. Reagan was asked what her favorite song was, which happened to be "Tie a Yellow Ribbon", so it was chosen as her entrance song. Ronald Reagan unsuccessfully challenged Gerald Ford, for the presidential nomination that year but came back in 1980 to claim the presidency itself. Ray Barnhart, a Reagan co-manager from Texas, criticized Mrs. Ford for having "danced a jig" with Orlando. Barbara Staff, another Texas co-chairman, called Betty Ford's behavior "a low, cheap shot". It was later confirmed that the Ford campaign slipped the song to the band when Nancy Reagan entered the hall. On October 12, 2015, with Telma Hopkins and Joyce Vincent Wilson present, Pacific Pioneer Broadcasters honored Orlando with their Art Gilmore Career Achievement Award at a celebrity luncheon.

Problem: Background: 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.
Context: On December 8, 2004, during the Devastation Across The Nation tour, Abbott was shot on-stage while performing with Damageplan at the Alrosa Villa in Columbus, Ohio. A crowd of approximately 250 had watched four support acts (two local bands entitled Volume Dealer and 12 Gauge, and the tour support Shadows Fall and The Haunted). Moments into Damageplan's set, 25-year-old former Marine Nathan Gale shot Abbott five times in the head with a 9 mm Beretta 92F pistol. Some in attendance initially believed the shooting was part of the act, but as Gale continued shooting, the audience quickly came to the realization that the event was not staged. Firing a total of 15 shots, Gale killed three other people and wounded seven more. Jeff "Mayhem" Thompson, the band's head of security, was killed tackling Gale, as was Alrosa Villa employee Erin Halk. Audience member Nathan Bray was killed while trying to perform CPR on Abbott and Thompson. It was rumored that one crowd member leapt in front of the gunman, saving the lives of several band members. Damageplan's drum technician, John "Kat" Brooks, was shot three times as he attempted to disarm Gale, but was overpowered and taken hostage in a headlock hold. Tour manager Chris Paluska was also injured. Responding within three minutes to a dispatch call made at 10:15pm, seven police officers entered through the front entrance and moved toward the stage. Officer James Niggemeyer came in through the back door, behind the stage. Gale only saw the officers in front of the stage; he did not see Niggemeyer, who was armed with a 12 gauge Remington 870 shotgun. Niggemeyer approached Gale from the opposite side of the stage past a group of security guards, and saw Gale lift his gun to Brooks' head, and fired a single shot as Gale noticed him. Gale was struck in the face with eight of the nine buckshot pellets and was killed instantly. Gale was found to have had 35 rounds of ammunition remaining. Two fans, including Mindy Reece, a certified nurse, administered CPR on Abbott until paramedics arrived, but were unable to revive him and he was pronounced dead at the scene. Early speculation about motive suggested that Gale, who was a Pantera fan, might have turned to violence in response to the breakup of the band, or the public dispute between Abbott and Pantera singer Phil Anselmo, but these were later ruled out by investigators. In VH1's documentary, Behind the Music, Damageplan's sound engineer Aaron Barnes stated that the whole time, after shooting Dimebag, Gale was looking for Vinnie, possibly planning to murder him too. Another conjecture was that Gale believed Abbott had stolen a song that he had written. About six months prior to the shooting, Gale got into an altercation at a Damageplan concert in Cincinnati where he damaged $5,000 worth of equipment while being removed from the stage by security.
