Following a highly successful small-group jazz concert at New York Town Hall on May 17, 1947, featuring Armstrong with trombonist/singer Jack Teagarden, Armstrong's manager Joe Glaser dissolved the Armstrong big band on August 13, 1947 and established a six-piece small group featuring Armstrong with (initially) Teagarden, Earl Hines and other top swing and dixieland musicians, most of them ex-big band leaders. The new group was announced at the opening of Billy Berg's Supper Club.
This group was called Louis Armstrong and his All Stars and included at various times Earl "Fatha" Hines, Barney Bigard, Edmond Hall, Jack Teagarden, Trummy Young, Arvell Shaw, Billy Kyle, Marty Napoleon, Big Sid Catlett, Cozy Cole, Tyree Glenn, Barrett Deems, Joe Darensbourg and the Filipino-American percussionist, Danny Barcelona. During this period, Armstrong made many recordings and appeared in over thirty films. He was the first jazz musician to appear on the cover of Time Magazine on February 21, 1949.
In 1964, he recorded his biggest-selling record, "Hello, Dolly!" The song went to No. 1 on the pop chart, making Armstrong (age 63) the oldest person to ever accomplish that feat. In the process, Armstrong dislodged The Beatles from the No. 1 position they had occupied for 14 consecutive weeks with three different songs.
Armstrong kept up his busy tour schedule until a few years before his death in 1971. In his later years he would sometimes play some of his numerous gigs by rote, but other times would enliven the most mundane gig with his vigorous playing, often to the astonishment of his band. He also toured Africa, Europe, and Asia under sponsorship of the US State Department with great success, earning the nickname "Ambassador Satch " and inspiring Dave Brubeck to compose his jazz musical The Real Ambassadors
While failing health restricted his schedule in his last years, within those limitations he continued playing until the day he died.
Louis Armstrong was the greatest of all Jazz musicians. Armstrong defined what it was to play Jazz. His amazing technical abilities, the joy and spontaneity, and amazingly quick, inventive musical mind still dominate Jazz to this day. Only Charlie Parker comes close to having as much influence on the history of Jazz as Louis Armstrong did. Like almost all early Jazz musicians, Louis was from New Orleans. He was from a very poor family and was sent to reform school when he was twelve after firing a gun in the air on New Year's Eve. At the school he learned to play cornet. After being released at age fourteen, he worked selling papers, unloading boats, and selling coal from a cart. He didn't own an instrument at this time, but continued to listen to bands at clubs like the Funky Butt Hall. Joe "King" Oliver was his favorite and the older man acted as a father to Louis, even giving him his first real cornet, and instructing him on the instrument. By 1917 he played in an Oliver inspired group at dive bars in New Orleans' Storyville section. In 1919 he left New Orleans for the first time to join Fate Marable's band in St. Louis. Marable led a band that played on the Strekfus Mississsippi river boat lines. When the boats left from New Orleans Armstrong also played regular gigs in Kid Ory's band. Louis stayed with Marable until 1921 when he returned to New Orleans and played in Zutty Singleton's. He also played in parades with the Allen Brass Band, and on the bandstand with Papa Celestin's Tuxedo Orchestra , and the Silver Leaf Band. When King Oliver left the city in 1919 to go to Chicago, Louis took his place in Kid Ory's band from time to time. In 1922 Louis received a telegram from his mentor Joe Oliver, asking him to join his Creole Jazz Band at Lincoln Gardens (459 East 31st Street) in Chicago. This was a dream come true for Armstrong and his amazing playing in the band soon made him a sensation among other musicians in Chicago. The New Orleans style of music took the town by storm and soon many other bands from down south made their way north to Chicago. While playing in Oliver's Creole Jazz Band, Armstrong met Lillian Hardin, a piano player and arranger for the band. In February of 1924 they were married. Lil was a very intelligent and ambitious woman who felt that Louis was wasting himself playing in Oliver's band.
