Problem: Bernard Mathew Leadon III (pronounced led-un; born July 19, 1947) is an American musician and songwriter, best known as a founding member of the Eagles. Prior to the Eagles, he was a member of three pioneering and highly influential country rock bands: Hearts & Flowers, Dillard & Clark, and the Flying Burrito Brothers. He is a multi-instrumentalist (guitar, banjo, mandolin, steel guitar, dobro) coming from a bluegrass background. He introduced elements of this music to a mainstream audience during his tenure with the Eagles.

Leadon was the last original member to join the Eagles, a band initially formed by guitarist/singer Glenn Frey, drummer/singer Don Henley, and former Poco bassist/singer Randy Meisner. Leadon is often credited with helping shape the band's early country-rock sound, bringing his strong sense of harmony as well as his country, bluegrass and acoustic sensibilities to the group. Instruments he played during his tenure in the band were electric guitar, B-Bender, acoustic guitar, banjo, mandolin, dobro and pedal steel guitar. Upon the release of their debut album, Eagles, the group met with near instantaneous success, due largely to the strength of their hit singles, "Take It Easy", "Peaceful Easy Feeling" and "Witchy Woman" (co-written by Leadon and Henley), all of which highlighted Leadon's multi-instrumental talent on electric guitar, B-Bender, banjo, and harmony vocals. Their follow-up, Desperado, was another strong country-rock venture highlighted by the classics "Tequila Sunrise" and the title track. Leadon had a prominent role on the album, but it was met by surprisingly lukewarm reviews and lackluster sales. As a result, the band attempted to distance itself from the "country rock" label for their third album On the Border. In doing so, Leadon encouraged the group to recruit his old friend, guitarist Don Felder, to the band. The result was the guitar-heavy top ten hit "Already Gone". The album also included "My Man", Leadon's touching tribute to his old bandmate and friend, Gram Parsons, who had died of a drug overdose the year prior at Joshua Tree National Monument in southeastern California. With the wild success of On the Border and its follow-up smash, One of These Nights, tension within the band grew, as Leadon grew increasingly frustrated by the band's direction away from his beloved country and bluegrass and toward album-oriented stadium rock. He famously quit the band in 1975 by pouring a beer over Glenn Frey's head. He later cited a need to get healthy and break the vicious cycle of touring, recording and heavy drug use that was rampant within the band. Upon his departure, Asylum Records released Their Greatest Hits (1971-1975), which highlighted the band's Leadon years and went on to become the biggest-selling album of all time for sales in excess of 42 million units, awarded to the band members by the RIAA. He was replaced by former James Gang guitarist/singer, Joe Walsh. Although it has long been believed that he left because he was dissatisfied with the band moving into rock and roll, Leadon denies it and said in 2013: "That's an oversimplification; it implies that I had no interest in rock or blues or anything but country rock. That's just not the case. I didn't just play Fender Telecaster. I played a Gibson Les Paul and I enjoyed rock & roll. That's evident from the early albums."

how old was he when he joined the Eagles?

Answer with quotes:

Problem: Giuseppe Fortunino Francesco Verdi (Italian: [dZu'zeppe 'verdi]; 9 or 10 October 1813 - 27 January 1901) was an Italian opera composer. He was born near Busseto to a provincial family of moderate means, and developed a musical education with the help of a local patron. Verdi came to dominate the Italian opera scene after the era of Vincenzo Bellini, Gaetano Donizetti, and Gioachino Rossini, whose works significantly influenced him. By his 30s, he had become one of the pre-eminent opera composers in history.

Having achieved some fame and prosperity, Verdi began in 1859 to take an active interest in Italian politics. His early commitment to the Risorgimento movement is difficult to estimate accurately; in the words of the music historian Philip Gossett "myths intensifying and exaggerating [such] sentiment began circulating" during the nineteenth century. An example is the claim that when the "Va, pensiero" chorus in Nabucco was first sung in Milan, the audience, responding with nationalistic fervour, demanded an encore. As encores were expressly forbidden by the government at the time, such a gesture would have been extremely significant. But in fact the piece encored was not "Va, pensiero" but the hymn "Immenso Jehova". The growth of the "identification of Verdi's music with Italian nationalist politics" perhaps began in the 1840s. In 1848, the nationalist leader Giuseppe Mazzini, (whom Verdi had met in London the previous year) requested Verdi (who complied) to write a patriotic hymn. The opera historian Charles Osborne describes the 1849 La battaglia di Legnano as "an opera with a purpose" and maintains that "while parts of Verdi's earlier operas had frequently been taken up by the fighters of the Risorgimento...this time the composer had given the movement its own opera" It was not until 1859 in Naples, and only then spreading throughout Italy, that the slogan "Viva Verdi" was used as an acronym for Viva Vittorio Emanuele Re D'Italia (Viva Victor Emmanuel King of Italy), (who was then king of Piedmont). After Italy was unified in 1861, many of Verdi's early operas were increasingly re-interpreted as Risorgimento works with hidden Revolutionary messages that perhaps had not been originally intended by either the composer or his librettists. In 1859, Verdi was elected as a member of the new provincial council, and was appointed to head a group of five who would meet with King Vittorio Emanuele II in Turin. They were enthusiastically greeted along the way and in Turin Verdi himself received much of the publicity. On 17 October Verdi met with Cavour, the architect of the initial stages of Italian unification. Later that year the government of Emilia was subsumed under the United Provinces of Central Italy, and Verdi's political life temporarily came to an end. Whilst still maintaining nationalist feelings, he declined in 1860 the office of provincial council member to which he had been elected in absentia. Cavour however was anxious to convince a man of Verdi's stature that running for political office was essential to strengthening and securing Italy's future. The composer confided to Piave some years later that "I accepted on the condition that after a few months I would resign." Verdi was elected on 3 February 1861 for the town of Borgo San Donnino (Fidenza) to the Parliament of Piedmont-Sardinia in Turin (which from March 1861 became the Parliament of the Kingdom of Italy), but following the death of Cavour in 1861, which deeply distressed him, he scarcely attended. Later, in 1874, Verdi was appointed a member of the Italian Senate, but did not participate in its activities.
