Question: Which bluegrass classic by Bill Monroe was covered by Elvis Presley, and also on Alan Jackson's 2013 Bluegrass Album?

<P0-S0>  The song has since been recorded by many artists, including Elvis Presley. <P0-S1> "Blue Moon of Kentucky" is a waltz written in 1946 by bluegrass musician Bill Monroe and recorded by his band, the Blue Grass Boys. <P0-S2>  In 2003, the song was chosen to be added to the United States Library of Congress National Recording Registry. <SEP> <P1-S0> The Bluegrass Album is the nineteenth studio album, and the first bluegrass album by American country music artist Alan Jackson. <P1-S1>  It was released on September 24, 2013 via Alan's Country Records and EMI Nashville. <P1-S2>  Jackson wrote eight songs for the album. <P1-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". <P1-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> <P2-S0> Bluegrass Album Band was a bluegrass supergroup, founded by Tony Rice and J.D. Crowe in 1980. <P2-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. <P2-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. <P2-S3>  On September 5, 2012, they announced a reunion show that was held at Bluegrass First Class in Asheville, NC on February 16, 2013. <P2-S4>  This event reunited the Bluegrass Album Band with their former manager and promoter, Milton Harkey. <SEP> <P3-S0>  (At the time, the Opry had bleachers for family just off stage). <P3-S1>  Curly Ray also played with the Stanley Brothers at a different time as their fiddler. <P3-S2>  Charlie returned to the Fiddlers briefly before becoming a member of Bill Monroe's Blue Grass Boys. <P3-S3>  During World War II, Ned was killed in action. <P3-S4>  None of them ever had a music lesson yet excelled on every instrument they touched. <P3-S5>  He also worked briefly as a sideman with the Osborne Brothers, although he did not record with them. <P3-S6> The Lonesome Pine Fiddlers (1938- 1966) were an early bluegrass band which included such notable "first generation" bluegrass musicians as Ezra Cline, Bobby Osborne, Paul Williams, Melvin Goins, Charlie Cline, Curly Ray Cline, Larry Richardson and for a short time Jimmy Martin. <P3-S7>  When Ezra brought the band to Pikeville, Kentucky, in November, Charlie rejoined Bill Monroe. <P3-S8>  The Clines came from a large family consisting of musically talented people. <P3-S9>  Charlie spent most of 1953 back with the Lonesome Pine Fiddlers working at WJR radio in Detroit. <P3-S10>  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. <P3-S11>  Bobby Osborne, Melvin Goins and Paul Williams were there to receive the bands award. <P3-S12>  Finally, on October 1, 2009, The Lonesome Pine Fiddlers got their due when they were inducted into the International Bluegrass Hall of Fame at the Ryman Theater (the original home of the Grand Ole Opry). <P3-S13>  Curly Ray was one of the best fiddlers in Bluegrass. <P3-S14>  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.
