Problem: Background: 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.
Context: 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."
Question: how old was he when he joined the Eagles?
Answer: 

Background: Franklin Joseph Lymon (September 30, 1942 - February 27, 1968), known professionally as Frankie Lymon, was an American rock and roll/rhythm and blues singer and songwriter, best known as the boy soprano lead singer of the New York City-based early rock and roll group The Teenagers. The group was composed of five boys, all in their early to mid-teens. The original lineup of the Teenagers, an integrated group, included three African-American members, Frankie Lymon, Jimmy Merchant, and Sherman Garnes; and two Puerto Rican members, Joe Negroni and Herman Santiago. The Teenagers' first single, 1956's "Why Do Fools Fall in Love," was also its biggest hit.
Context: Lymon's troubles extended to others after his death. After R&B singer Diana Ross returned "Why Do Fools Fall in Love" to the Top Ten in 1981, a major controversy concerning Lymon's estate ensued. Zola Taylor, Elizabeth Waters and Emira Eagle each approached Morris Levy, the music impresario who retained possession of Lymon's copyrights and his royalties, claiming to be Lymon's rightful widow; Lymon had neglected to divorce either of them. The complex issue resulted in lawsuits and counter-lawsuits, and in 1986 the first of several court cases concerning the ownership of Lymon's estate began.  Trying to determine who was indeed the lawful Mrs. Frankie Lymon was complicated by more issues. Waters was already married when she married Lymon; she had separated from her first husband, but their divorce was finalized in 1965, after she had married Lymon. Taylor claimed to have married Lymon in Mexico in 1965, but could produce no acceptable evidence of their union. Lymon's marriage to Eagle, on the other hand, was properly documented as having taken place at Beulah Grove Baptist Church in Augusta, Georgia, in 1967; however, the singer was still apparently twice-married and never divorced when he married Eagle. The first decision was made in Waters' favor; Eagle appealed, and in 1989, the Appellate Division of the New York State Supreme Court reversed the original decision and awarded Lymon's estate to Eagle.  However, the details of the case brought about another issue: whether Morris Levy was deserving of the songwriting co-credit on "Why Do Fools Fall in Love". Although early single releases of "Why Do Fools Fall in Love" credit Frankie Lymon, Herman Santiago and Jimmy Merchant as co-writers, later releases and cover versions were attributed to Lymon and George Goldner. When Goldner sold his music companies to Morris Levy in 1959, Levy's name began appearing as co-writer of "Why Do Fools Fall in Love" in place of Goldner's. Lymon was never paid his songwriting royalties during his lifetime; one result of Emira Eagle's legal victory was that Lymon's estate would finally begin receiving monetary compensation from his hit song's success. In 1987, Herman Santiago and Jimmy Merchant, both then poor, sued Morris Levy for their songwriting credits. In December 1992, the United States federal courts ruled that Santiago and Merchant were co-authors of "Why Do Fools Fall in Love". However, in 1996 the ruling was reversed by the Court of Appeals for the 2nd Circuit on the basis of the statute of limitations: copyright cases must be brought before a court within three years of the alleged civil violation, and Merchant and Santiago's lawsuit was not filed until 30 years later. Authorship of "Why Do Fools Fall in Love" currently remains in the names of Frankie Lymon and Morris Levy.
Question: who won the suit?
Answer:
the Appellate Division of the New York State Supreme Court reversed the original decision and awarded Lymon's estate to Eagle.
