IN: Lester Willis Young (August 27, 1909 - March 15, 1959), nicknamed "Pres" or "Prez", was an American jazz tenor saxophonist and occasional clarinetist. Coming to prominence while a member of Count Basie's orchestra, Young was one of the most influential players on his instrument. In contrast to many of his hard-driving peers, Young played with a relaxed, cool tone and used sophisticated harmonies, using what one critic called "a free-floating style, wheeling and diving like a gull, banking with low, funky riffs that pleased dancers and listeners alike". Known for his hip, introverted style, he invented or popularized much of the hipster jargon which came to be associated with the music.

In 1933 Young settled in Kansas City, where after playing briefly in several bands, he rose to prominence with Count Basie. His playing in the Basie band was characterized by a relaxed style which contrasted sharply with the more forceful approach of Coleman Hawkins, the dominant tenor sax player of the day. One of Young's key influences was Frank Trumbauer, who came to prominence in the 1920s with Paul Whiteman and played the C-melody saxophone (between the alto and tenor in pitch). Young left the Basie band to replace Hawkins in Fletcher Henderson's orchestra. He soon left Henderson to play in the Andy Kirk band (for six months) before returning to Basie. While with Basie, Young made small-group recordings for Milt Gabler's Commodore Records, The Kansas City Sessions. Although they were recorded in New York (in 1938, with a reunion in 1944), they are named after the group, the Kansas City Seven, and comprised Buck Clayton, Dicky Wells, Basie, Young, Freddie Green, Rodney Richardson, and Jo Jones. Young played clarinet as well as tenor in these sessions. Young is described as playing the clarinet in a "liquid, nervous style." As well as the Kansas City Sessions, his clarinet work from 1938-39 is documented on recordings with Basie, Billie Holiday, Basie small groups, and the organist Glenn Hardman. Billie and Lester met at a Harlem jam session in the early 30s and worked together in the Count Basie band and in nightclubs on New York's 52nd St. At one point Lester moved into the apartment Billie shared with her mother, Sadie Fagan. Holiday always insisted their relationship was strictly platonic. She gave Lester the nickname "Prez" after President Franklin Roosevelt, the "greatest man around" in Billie's mind. Playing on her name, he would call her "Lady Day." Their famously empathetic classic recordings with Teddy Wilson date from this era. After Young's clarinet was stolen in 1939, he abandoned the instrument until about 1957. That year Norman Granz gave him one and urged him to play it (with far different results at that stage in Young's life--see below).

When did he join count basie?

OUT: In 1933 Young settled in Kansas City, where after playing briefly in several bands, he rose to prominence with Count Basie.

input: 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."
