IN: Duke was born in New York City, the only child of tobacco and hydroelectric power tycoon James Buchanan Duke and his second wife, Nanaline Holt Inman, widow of Dr. William Patterson Inman. At his death in 1925, the elder Duke's will bequeathed the majority of his estate to his wife and daughter, along with $17 million in two separate clauses of the will, to The Duke Endowment he had created in 1924. The total value of the estate was not disclosed, but was estimated variously at $60 million to $100 million (equivalent to $837 million to $1.395 billion in 2018), the majority culled from J.B. Duke's holds in Lucky Strike cigarettes. Duke spent her early childhood at Duke Farms, her father's 2,700-acre (11 km2) estate in Hillsborough Township, New Jersey.

Duke married twice, the first time in 1935 to James H. R. Cromwell, the son of Palm Beach society doyenne Eva Stotesbury. Cromwell, a New Deal advocate like his wife, used her fortune to finance his political career. In 1940 he served several months as U.S. Ambassador to Canada and ran unsuccessfully for the U.S. Senate. The couple had a daughter, Arden, who died one day after her birth. They divorced in 1943.  On September 1, 1947, while in Paris, Duke became the third wife of Porfirio Rubirosa, a diplomat from the Dominican Republic. She reportedly paid his second wife, actress Danielle Darrieux, $1 million to agree to an uncontested divorce. Because of her great wealth, Duke's marriage to Rubirosa attracted the attention of the U.S. State Department, which cautioned her against using her money to promote political agenda. Further, there was concern that in the event of her death, a foreign government could gain too much leverage. Therefore, Rubirosa had to sign a pre-nuptial agreement; during the marriage, though, she gave Rubirosa several million dollars in gifts, including a stable of polo ponies, sports cars, a converted B-25 bomber, and, in the divorce settlement, a 17th-century house in Paris. One of Doris Duke's best friends was Brazilian socialite and "jetsetter" Aimee de Heeren.  She reportedly had numerous affairs, with, among others, Duke Kahanamoku, Errol Flynn, Alec Cunningham-Reid, General George S. Patton, Joe Castro, and Louis Bromfield.  Duke posted a bail of $5,000,000 for her friend, former Philippine First Lady Imelda Marcos after the latter was arrested for racketeering.

IN: Sudano was born in Flatbush, Brooklyn, New York to Margaret Alessio (1924-2012) and Louis Sudano (1923-2008). At the age of four, Sudano learned to play his first instrument, the accordion. He later taught himself to play piano and guitar. He soon developed a reputation in his community as a talented musician and got his first paid gig at the age of twelve.

Sudano was signed as a solo artist by RCA and released his first record The Fugitive Kind in 1981. It featured a song "Starting Over Again" that Sudano had co-written with his wife Donna Summer about his parents' divorce. In 1980, the song was recorded and released by Dolly Parton on the album Dolly, Dolly, Dolly, and hit #1 on the U.S. country charts on May 24, 1980. The song was recorded by Reba McEntire in 1995. Sudano spent two decades managing Summer's career. They toured together, with Sudano playing keyboards and singing background vocals.  In 1984, Sudano wrote "Tell Me I'm Not Dreamin' (Too Good to Be True)" with Michael Omartian. Jermaine Jackson and Michael Jackson recorded the song as a duet for the album Jermaine Jackson. The song was nominated at the 1985 Grammy Awards for Best R&B Performance by a Duo or Group with Vocals. In 1988, the song was covered by Robert Palmer. During the same period, he co-wrote four songs on Summer's She Works Hard For The Money album. One of which was the adult contemporary hit, "Love Has A Mind of Its Own". In 1986, he co-wrote "Closest Thing To Perfect", the title track for the John Travolta, Jamie Lee Curtis movie Perfect.  In 2004, Sudano released a second solo record called Rainy Day Soul and scored three top ten Adult Contemporary hits and earned him the New Music Weekly 2004 Adult Contemporary Artist of the Year award.  Sudano's third solo record Life and the Romantic was released in 2009 and won the New Music Weekly Adult Contemporary Song of the Year award for the track "It's Her Wedding Day" which Sudano wrote about his daughter Amanda's marriage to her Johnnyswim bandmate Abner Ramirez. Johnnyswim performed with Sudano on the track "Morning Song". The song "A Glass of Red & the Sunset" and "Beyond Forever" have performed well on the smooth jazz charts. In 2014, after the death of his wife, Sudano released the CD With Angels On A Carousel. Here he delicately and soulfully crafted songs that reflected his experience through this difficult experience.  In the fall of 2015, Sudano released a new album, The Burbank Sessions. While playing shows throughout 2014 with his newly formed Candyman Band, he continued writing and incorporated the new material into the sets. Once the dates for the year were concluded, he went into his rehearsal studio and recorded these new songs as he performed them, giving the CD a spontaneous and almost live feel. He followed the release with a run of US shows and an extensive European tour.

Did he sing any duets with Donna Summer?
