One of the most popular singers in the United States from the mid-to-late 20th century, Newton remains one of the best-known entertainers in Las Vegas and has performed there since 1963.

[1] As a teenager, Newton first performed in Las Vegas in the late 1950s and was mentored by some of the nation's biggest artists including Frank Sinatra, Bobby Darin and Elvis Presley.

In 1963, he achieved headliner status at the Flamingo, a casino hotel in Las Vegas, and soon became one of the city's most popular performers.

The Washington Post describes Newton as "America's number one night club act" and at his peak being more prominent in Las Vegas than both Sinatra and Presley.

His well known songs include "Danke Schoen" (1963), "Summer Wind" (1965), "Red Roses for a Blue Lady" (1965), "Daddy, Don't You Walk So Fast" (1972) and "Years" (1980).

[4][11][12] Soon after arriving in Phoenix, the brothers performed in a local television talent show Lew King Rangers and won.

[10] The brothers, as the Rascals in Rhythm, appeared with the Grand Ole Opry roadshows and on ABC-TV's Ozark Jubilee; performed in front of then-president Dwight D. Eisenhower[13] and auditioned unsuccessfully for Ted Mack's Original Amateur Hour.

[3] In the spring of 1958, near the end of his junior year of high school, a Las Vegas booking agent saw the two Newton brothers performing on their local TV show and took them back for an audition.

Impressed with their audition, the booking agent signed Newton, then age 15, and his brother, as part of a two-week contract to perform in Las Vegas at the Flamingo.

[10] On closing night, Newton and his brother were offered a one-year contract to continue performing in Las Vegas.

To pursue his music career, Newton left North High School just before finishing his junior year.

[4][10] At age 18, Newton intended to join the US military but because of his asthma he was given a 1-Y rejection meaning he was qualified to serve only in the event of a major emergency.

Newton credits his ability to base his performances on what the crowd wanted to hear for his early success in Las Vegas.

In the early to mid-1960s, Newton also acted and sang as "Andy," the baby-faced Ponderosa ranchhand, on the classic western TV series Bonanza.

Many other prominent entertainment icons such as Lucille Ball, Danny Thomas, George Burns, and Jack Benny lent Newton their support.

Following the death of Elvis Presley and the aging of many members of the Rat Pack, Newton emerged as the biggest entertainer in Las Vegas.

[3] In 1972, his recording of "Daddy, Don't You Walk So Fast" sold more than one million copies and was awarded a gold disc by the RIAA in July 1972.

[20] From 1980 through 1982, The Beach Boys and The Grass Roots performed Independence Day concerts on the National Mall in Washington, D.C., attracting large crowds.

[21][22] However, in April 1983, James G. Watt, President Reagan's Secretary of the Interior, banned Independence Day concerts on the Mall by such groups.

Watt said that "rock bands" that had performed on the Mall on Independence Day in 1981 and 1982 had encouraged drug use and alcoholism and had attracted "the wrong element" who would threaten individuals and families attending any similar events in the future.

[22] Watt then announced that Newton, a friend and supporter of President Reagan, would perform at the Mall's 1983 Independence Day celebration.

Newton did not perform his trademark songs "Danke Schoen" or "Red Roses for a Blue Lady," however he closed the show with a special finale of "MacArthur Park" which culminated with an onstage rainfall.

[28] During the 1990s, Newton began performing at other casinos as their headliner, including Bally's, Caesars Palace, and MGM Grand Las Vegas.

Newton was featured on the 2007 fall season of Dancing with the Stars partnered with two-time champion Cheryl Burke.

[30] In 2010, Newton took a five-year hiatus to spend time with his family and prepare his voice for later shows in Las Vegas.

[45] In 1992, Newton filed for Chapter 11 bankruptcy to reorganize an estimated $20 million in debts, much of which was accumulated while suing NBC for libel; he claimed the network had reported that he partnered with the Mafia to buy the Aladdin.

[49] In February 2010, Bruton Smith sued Newton, claiming he was delinquent on a loan he had personally guaranteed, then bought from Bank of America.

The developer claimed that he had invested $50 million on the project, but that Newton had failed to move out and had deliberately thwarted construction efforts.

[53] The property remained on the market, until 2015, when Newton reached an accord with Lacy Harber, the businessman who owned 70% of the corporation that had purchased Casa de Shenandoah to turn it into a museum.

Newton and his family moved back into the property, and in September 2015, after construction of a museum to house memorabilia, it was opened for public tours.
