In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Example input: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Example output: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.
Q: Passage: Leon Bismark "Bix" Beiderbecke (March 10, 1903 – August 6, 1931) was an American jazz cornetist, pianist, and composer.
Beiderbecke was one of the most influential jazz soloists of the 1920s, a cornet player noted for an inventive lyrical approach and purity of tone. His solos on seminal recordings such as "Singin' the Blues" and "I'm Coming, Virginia" (both 1927) demonstrate a gift for extended improvisation that heralded the jazz ballad style, in which jazz solos are an integral part of the composition. Moreover, his use of extended chords and an ability to improvise freely along harmonic as well as melodic lines are echoed in post-WWII developments in jazz. "In a Mist" (1927) is the best known of Beiderbecke's published piano compositions, and the only one that he recorded. His piano style reflects both jazz and classical (mainly impressionist) influences. All five of his piano compositions were published by Robbins Music during his lifetime.
A native of Davenport, Iowa, Beiderbecke taught himself to play the cornet largely by ear, leading him to adopt a non-standard fingering technique that informed his unique style. He first recorded with Midwestern jazz ensemble The Wolverines in 1924, after which he played briefly for the Detroit-based Jean Goldkette Orchestra before joining Frankie "Tram" Trumbauer for an extended engagement at the Arcadia Ballroom in St. Louis, also under the auspices of Goldkette's organisation. Beiderbecke and Trumbauer joined Goldkette's main band at the Graystone Ballroom in Detroit in 1926. The band toured widely and famously played a set opposite Fletcher Henderson at the Roseland Ballroom in New York City in October 1926. He made his greatest recordings in 1927. The Goldkette band folded in September 1927 and, after briefly joining bass saxophone player Adrian Rollini's band in New York, Trumbauer and Beiderbecke joined America's most popular dance band: Paul Whiteman and his Orchestra.
A:
What is the full name of the sax player who's band was joined by one of the most influential jazz soloists of the 1920s after the Goldkette band folded?
