A talent scout for Lawrence Welk, who saw Pete Fountain performing at the Pier 600, invited him to join the Welk’s orchestra in Los Angeles, where he re-located for two years becoming well-known for his many solos on Welk’s ABC television show, The Lawrence Welk Show. Fountain was rumored to have quit when Welk refused to let him “jazz up” a Christmas carol on the 1958 Christmas show. Other accounts, including one in Fountain’s autobiography A Closer Walk With Pete Fountain, indicate he in fact played a jazzy rendition of “Silver Bells” on the show that upset Welk, leading to Fountain’s departure in early 1959. In an interview, Fountain said he left The Lawrence Welk Show because “Champagne and bourbon don’t mix.” Fountain was hired by Decca Records A&R head Charles “Bud” Dant and went on to produce 42 hit albums with Dant. After Welk’s death, Fountain would occasionally join with the Welk musical family for reunion shows. Pete Fountain returned to New Orleans, played with The Dukes of Dixieland, then began leading bands under his own name. He owned his own club in the French Quarter in the 1960s and 1970s. He later acquired “Pete Fountain’s Jazz Club” at the Riverside Hilton in downtown New Orleans. The New Orleans Jazz Club presented “Pete Fountain Day” on October 19, 1959, with celebrations honoring the pride of their city, concluding with a packed concert that evening. His Quintett was made up of his studio recording musicians, Stan Kenton’s bassist Don Bagley, vibeist Godfrey Hirsch, pianist Merle Koch, and the double bass drummer Jack Sperling. Fountain brought these same players together in 1963 when they played the Hollywood Bowl. Pete would make the trek to Hollywood many times, appearing on The Tonight Show Starring Johnny Carson 56 times.

Pete Fountain opened his club, the French Quarter Inn, located in the heart of the famed French Quarter district, at 800 Bourbon Street, in the spring of 1960. His group members were Oliver “Stick” Felix on bass, John Probst on piano, Paul Guma on guitar, Godfrey Hirsch on vibes, and Jack Sperling on drums. In no time at all, major entertainers found their way there. Cliff Arquette and Jonathan Winters were there on opening night and performed their comedy routines. Over the next few years Frank Sinatra, Phil Harris, Carol Lawrence and Robert Goulet, Keely Smith, Robert Mitchum, and Brenda Lee, among many others, came to the club. Many would perform with the band, and Brenda Lee’s sit-in resulted in a duet record album recorded by her and Pete. Benny Goodman came to the club twice, but without bringing his clarinet. His greatest friendly rivalry was with trumpeter Al Hirt, whose club was down the street from Fountain’s. They stole musicians from each other, and sometimes came into each other’s clubs and played together. They were good friends who came up together and later recorded several albums together. In 2003, Fountain closed his club at the Hilton with a performance before a packed house filled with musical friends and fans. He began performing two nights a week at Casino Magic in Bay St. Louis, Mississippi, where he also had a home (later destroyed by Hurricane Katrina). After heart surgery in 2006, he performed at [the] JazzFest, and helped reopen the Bay St. Louis Casino in Bay St. Louis, MS. It has since been renamed the Hollywood Casino. He performed his last show at the Hollywood Casino on December 8, 2010, before returning to help reopen the resort in 2014, by which point he was mostly retired.

Pete Fountain’s clarinet work was noted for his sweet fluid tone. He recorded over 100 LPs and CDs under his own name, some in the Dixieland style, many others with only peripheral relevance to any type of jazz. The distinctive Fountain sound — more woody than most — came from the crystal mouthpieces he played with since 1949. His first crystal mouthpiece was actually Irving Fazola’s, given to Pete by Fazola’s mother after Faz’s death, because she had heard him play and noted how he played like her son. That mouthpiece was shattered on the bandstand one night when Pete had played his solo and was standing by as trumpeter George Girard played his [own solo], and Girard brought his trumpet down suddenly on top of the mouthpiece. Pete kept the shattered mouthpiece, and played other crystal mouthpieces ever since. Fountain led the Pete Fountain Quintett, a New Orleans French Quarter jazz band of Fountain and his Creole-style music. The “Quintett” had many musicians over the years, but primarily recorded with Jack Sperling on drums, bassists Don Bagley or Morty Corb, vibeist Godfrey Hirch, and pianists Merle Kock or Stan Wrightsman. Pete Fountain married Beverly Lang on October 27, 1951; they remained married for sixty-five years until his death. They have two sons and a daughter: Kevin, Jeffrey, and Dahra. Dahra’s husband, Benny Harrell, was Fountain’s manager in his later years. Fountain died in his hometown on August 6, 2016, at the age of eighty-six. He had suffered from heart problems and was in hospice care when he died.
