<P0-S0>  When the Pine Fiddlers resumed regular daily broadcasts, Charlie, who played multiple instruments, joined them on a regular basis. <P0-S1>  During World War II, Ned was killed in action. <P0-S2>  He also worked briefly as a sideman with the Osborne Brothers, although he did not record with them. <P0-S3>  When Ezra brought the band to Pikeville, Kentucky, in November, Charlie rejoined Bill Monroe. <P0-S4>  In 1954, Charlie did a session, playing lead guitar, with the Stanley Brothers and also another one on RCA with the Fiddlers, although he was not otherwise working with them at the time. <P0-S5>  For reasons unknown, Bobbi and Geraldine never joined the band on the road but often joined in at home, especially when notable Country singers, such as Bill Monroe, Lester Flatt and Earl Scruggs, and Hank Williams, came visiting. <P0-S6>  The group was started by Ezra Cline and Curly Ray Cline and was originally named "Cousin Ezra and the Lonesome Pine Fiddlers". <P0-S7>  Curly Ray also played with the Stanley Brothers at a different time as their fiddler. <P0-S8>  None of them ever had a music lesson yet excelled on every instrument they touched. <P0-S9>  Ray and Charlie's father, Charlie, was a talented banjo player and the women in the family, Geraldine and Bobbi, were great singers. <P0-S10>  By 1958, Charlie (electric lead guitar) and his wife, Lee (electric bass), had rejoined Ezra and Curly Ray in the Lonesome Pine Fiddlers, who were experimenting with a more modern sound and working a TV show in Huntington, West Virginia, in addition to daily radio in Pikeville. <P0-S11>  During 1952-1955, Charlie worked off and on with Monroe, recording some 38 songs, all on Decca. <P0-S12>  The Clines came from a large family consisting of musically talented people. <P0-S13>  Charlie returned to the Fiddlers briefly before becoming a member of Bill Monroe's Blue Grass Boys. <P0-S14>  This most talented family of musicians were the best, surpassed by none. <SEP> <P1-S0> "Blue Moon of Kentucky" is a waltz written in 1946 by bluegrass musician Bill Monroe and recorded by his band, the Blue Grass Boys. <P1-S1>  The song has since been recorded by many artists, including Elvis Presley. <P1-S2>  In 2003, the song was chosen to be added to the United States Library of Congress National Recording Registry. <SEP> <P2-S0> The Bluegrass Album is the nineteenth studio album, and the first bluegrass album by American country music artist Alan Jackson. <P2-S1>  It was released on September 24, 2013 via Alan's Country Records and EMI Nashville. <P2-S2>  Jackson wrote eight songs for the album. <P2-S3>  It also includes covers of The Dillards' "There Is a Time", John Anderson's "Wild and Blue" and Bill Monroe's "Blue Moon of Kentucky". <P2-S4>  Also included is a re-recording of "Let's Get Back to Me and You" from his 1994 album "Who I Am", marking the second time Jackson has included two versions of the same song on two different albums ("A Woman's Love" was originally recorded for "High Mileage" and was later re-recorded for "Like Red on a Rose"). <SEP> <P3-S0> Bluegrass Album Band was a bluegrass supergroup, founded by Tony Rice and J.D. Crowe in 1980. <P3-S1>  Originally, there was no intention to build a permanent group and the main reason for the collaboration was to record a solo album for Tony Rice. <P3-S2>  They found that this cooperation could work and the result was an album called "The Bluegrass Album", released in 1981, with 5 more volumes of music to follow. <P3-S3>  On September 5, 2012, they announced a reunion show that was held at Bluegrass First Class in Asheville, NC on February 16, 2013. <P3-S4>  This event reunited the Bluegrass Album Band with their former manager and promoter, Milton Harkey.
