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.
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.

Orlando sang under the condition that his name not be associated with the project, so it was released under the simple name of "Dawn",

Walter Bruce Willis was born on March 19, 1955, in the town of Idar-Oberstein, West Germany. His father, David Willis, was an American soldier. His mother, Marlene, was German, born in Kassel. Willis is the oldest of four children with a sister named Florence and two brothers, Robert (who is deceased) and David.
Throughout his film career, Willis has depicted several military characters in films such as In Country, The Siege, Hart's War, Tears of the Sun, Grindhouse, and G.I. Joe: Retaliation. Growing up in a military family, Willis has publicly sold Girl Scout cookies for the United States armed forces. In 2002, Willis's then 8-year-old daughter, Tallulah, suggested that he purchase Girl Scout cookies to send to troops. Willis purchased 12,000 boxes of cookies, and they were distributed to sailors aboard USS John F. Kennedy and other troops stationed throughout the Middle East at the time.  In 2003, Willis visited Iraq as part of the USO tour, singing to the troops with his band, The Accelerators. Willis considered joining the military to help fight the second Iraq war, but was deterred by his age. It was believed he offered $1 million to any noncombatant who turns in terrorist leaders Osama bin Laden, Ayman al-Zawahiri, or Abu Musab al-Zarqawi; in the June 2007 issue of Vanity Fair, however, he clarified that the statement was made hypothetically and not meant to be taken literally. Willis has also criticized the media for its coverage of the war, complaining that the press were more likely to focus on the negative aspects of the war:  I went to Iraq because what I saw when I was over there was soldiers--young kids for the most part--helping people in Iraq; helping getting the power turned back on, helping get hospitals open, helping get the water turned back on and you don't hear any of that on the news. You hear, 'X number of people were killed today,' which I think does a huge disservice. It's like spitting on these young men and women who are over there fighting to help this country.  Willis stated in 2005 that he wanted to "make a pro-war film in which American soldiers will be depicted as brave fighters for freedom and democracy." The film would follow members of Deuce Four, the 1st Battalion, 24th Infantry, who spent considerable time in Mosul and were decorated heavily for it. The film is to be based on the writings of blogger Michael Yon, a former United States Army Special Forces soldier who was embedded with Deuce Four and sent regular dispatches about their activities. Willis described the plot of the film as "these guys who do what they are asked for very little money to defend and fight for what they consider to be freedom."

Has he done any other things for troops besides the USO tour?
