Question: Sleigh Ride is a piece of music written by composer described by whom as "one of the great American masters of light orchestral music"?
Context: Leon Jessel, or Léon Jessel (January 22, 1871 – January 4, 1942) was a German composer of operettas and light classical music pieces.  Today he is best known internationally as the composer of the popular jaunty march "The Parade of the Tin Soldiers", also known as "The Parade of the Wooden Soldiers".  Jessel was a prolific composer who wrote hundreds of light orchestral pieces, piano pieces, songs, waltzes, mazurkas, marches, choruses, and other salon music.  He achieved considerable acclaim with a number of his operettas — in particular "Schwarzwaldmädel" ("Black Forest Girl"), which remains popular to this day. Wrexham Symphony Orchestra was founded in 1969 by the late Bryn Williams, then senior lecturer of Music at Cartrefle Teacher Training College in Wrexham.  He gathered together a small number of local string players, led by Keith Dawber, to put on a concert, and they were billed as the “Clywedog Ensemble”.  The Wrexham and District Orchestral Society was formed after the initial concert when they decided to expand the group to include woodwind and brass players.  The performing arm of this society came to be known as Wrexham Orchestra.  It was not until 1992 that the orchestra obtained its present name of Wrexham Symphony Orchestra, or WSO for short.  WSO has grown to a present-day membership numbering over sixty players and regularly attracts professional guest conductors and high-profile soloists.  This increase in membership has allowed the orchestra to undertake increasingly ambitious programmes of music.  Since 1997, the orchestra has been resident at the NEWI William Aston Hall in Wrexham.  1997 also saw the orchestra make a successful bid for funding to the Lottery unit of the Arts Council of Wales.  The percussion equipment bought with this grant is now housed at the NEWI William Aston Hall.  The orchestra was given charitable status in the early 1990s, which has enabled it to raise money for many other charities.  Many local charities have benefited, and over the years many thousands of pounds have been donated.  In 1999 the orchestra was presented with a community award for its charity work by British Steel.  In 2004 the WSO was inaugurated Orchestra in Residence at the William Aston Hall, NEWI (now Glyndŵr University).  The year also saw the orchestra presented with a workshop alongside players from the BBC National Orchestra of Wales, and to receive a grant towards music hire and expenditure from the Arts Council of Wales.  In December 2004, the WSO appeared on CD performing Leroy Anderson’s “Sleigh Ride”, part of a charity disc for Children in Need, in conjunction with many local schools and the recording course at the North East Wales Institute.  2006 saw the orchestra receive a second grant through the Welsh Amateur Music Federation (WAMF) which has enabled the orchestra to purchase a greatly needed “Clavinova” keyboard to enhance the orchestra’s repertoire and functionality.  2007 saw the formation of the Wrexham Symphony Chorus, a sister organisation inaugurated to widen the repertoire of the orchestra and to give local singers more opportunity to perform with full Symphony Orchestra.

His script for "Finding Lucy" was also nominated for Best Documentary Script by the Writers Guild of America.  Wagner also co-produced another PBS "American Masters" documentary, "Rod Serling: Submitted for your Approval", and his script for that film bio, co-written with John Goff, was again nominated for Best Documentary Script by the Writers Guild of America.  The Serling documentary also won a Bronze Plaque at the Columbus Film Festival and a Cine Gold Eagle.  Wagner also composed the music for the Academy Award nominated film, "" which aired on HBO. "Sleigh Ride" is a popular light orchestral Christmas music standard composed by Leroy Anderson.  The composer had the original idea for the piece during a heat wave in July 1946 and finished the work in February 1948.  It was originally an instrumental piece; the lyrics, about someone asking another to join them for a ride in a sleigh, were written by Mitchell Parish in 1950.  The orchestral version was first recorded in 1949 by Arthur Fiedler and the Boston Pops Orchestra.  Sleigh Ride was a hit record on RCA Victor Red Seal 49-0515 (45 rpm) / 10-1484 (78 rpm), and has become a signature song for the orchestra.  The 45 rpm version was originally issued on red vinyl.  The Pops has also recorded the song with John Williams, their conductor from 1979 to 1995, and Keith Lockhart, their current conductor. The Turangalîla-Symphonie is a large-scale piece of orchestral music by Olivier Messiaen (1908–92).  It was written from 1946 to 1948 on a commission by Serge Koussevitzky for the Boston Symphony Orchestra.  The premiere was in Boston on 2 December 1949, conducted by Leonard Bernstein.  The commission did not specify the duration, orchestral requirements or style of the piece, leaving the decisions to the composer.  Koussevitzky was billed to conduct the premiere, but fell ill, and the task fell to the young Bernstein.  Bernstein has been described as "the ideal conductor for it, and it made Messiaen's name more widely known".  Yvonne Loriod, who later became Messiaen's second wife, was the piano soloist, and Ginette Martenot played the ondes Martenot for the first and several subsequent performances.  From 1953, Yvonne's sister Jeanne Loriod was the ondes Martenot player in many performances and recordings. "Like Someone in Love" is a popular song composed in 1944 by Jimmy Van Heusen, with lyrics by Johnny Burke.  It was written (along with "Sleigh Ride in July") for the 1944 film "Belle of the Yukon", where it was sung by Dinah Shore.  It was a hit for Bing Crosby in March 1945, reaching #15, and has since become a jazz standard. Leroy Anderson ( ~ ); (June 29, 1908 – May 18, 1975) was an American composer of short, light concert pieces, many of which were introduced by the Boston Pops Orchestra under the direction of Arthur Fiedler.

Herbert "Herb" Rehbein (15 April 1922 – 28 July 1979) was a German songwriter, composer and arranger of light orchestral music.  Together with his friend and collaborator Bert Kaempfert, he was posthumously inducted into the Songwriters Hall of Fame in 1993. The Alpine Sleigh Ride was a dark ride located in the Alpine Valley section of AstroWorld in Houston, Texas.  It was one of the original attractions of the park and operated from 1968 until the end of the 1983 operating season.  Featuring a ride control system and vehicles (ArrowGlide) designed by Arrow Dynamics, the attraction's initial concept and design was by amusement park planner and architect Randall Duell.  Duell’s company had been hired by Judge Roy Hofheinz to plan AstroWorld.  The attraction took riders through an alpine themed forest before reaching the show building which was designed to resemble a large mountain capped with snow. Albert William Ketèlbey ( ; born Ketelbey; 9 August 1875 – 26 November 1959) was an English composer, conductor and pianist, best known for his short pieces of light orchestral music.  He was born in Birmingham and moved to London in 1889 to study at Trinity College of Music.
