The Magic Window (also known as The House with the Magic Window) was an American children's television program broadcast on ABC affiliate WOI-TV in Ames, Iowa from 1951 to 1994.
 With a run of 43 years, it was the longest running children's television program in American history.
 ("Bozo's Circus" technically had a longer run; however, it was made in many different local markets by different producers.)
 Producer Dick Hartzell and WOI TV artist Joy (Ringham) Munn developed the show as an educational children's program, which featured handicraft activities, news items, and birthday recognition for the children viewing the show.
 Joy co-hosted the show with Craighton Knau for the first season (1951-1952), which was 30 minutes long and aired 3 times per week.
 During the second season, she became the sole host of the program.
 For that season the show was 15 minutes long and aired 5 days per week.
 Joy left the show in 1953.
 For all but the first three years of the show, it was hosted by Betty Lou Varnum, another pioneer in central-Iowa broadcasting.
Alexander Alexandrovich Ilyinsky (Russian: Алекса́ндр Алекса́ндрович Ильи́нский ; 24 January [O.S. 12 January] 1859 23 February 1920) was a Russian music teacher and composer, best known for the "Lullaby (Berceuse)", Op. 13, No. 7, from his orchestral suite "Noure and Anitra", and for the opera "The Fountain of Bakhchisaray" set to Pushkin's poem of the same name.
Closing credits or end credits are a list of the cast and crew of a particular motion picture, television program, or video game.
 Where opening credits appear at the beginning of a work, closing credits appear close to, or at the very end of a work.
 A full set of credits can include the cast and crew, but also production sponsors, distribution companies, works of music licensed or written for the work, various legal disclaimers, such as copyright and more.
 Some long-running productions list "production babies".
Pyotr Ilyich Tchaikovsky composed his Orchestral Suite No. 3 in G, Op. 55 in 1884, writing it concurrently with his Concert Fantasia in G, Op. 56, for piano and orchestra.
 The originally intended opening movement of the suite, "Contrastes", instead became the closing movement of the fantasia.
 Both works were also intended initially as more mainstream compositions than they became; the fantasia was intended as a piano concerto, while the suite was conceived as a symphony.
"Fool's Overture" is the closing track from Supertramp's 1977 album "Even in the Quietest Moments...".
 Written and sung by guitarist/keyboardist Roger Hodgson, the song is a collage of progressive instrumentation and sound samples.
 First there are excerpts of Winston Churchill's famous 4 June 1940 House of Commons speech regarding Britain's involvement in World War II ("Never Surrender"), and later sounds of police cars and bells from the London's Big Ben clock tower are heard.
 The flageolet-sounding instrument plays an excerpt from Gustav Holst's "Venus", from his orchestral suite "The Planets".
 There is also a reading of the first verse of William Blake's poem "And did those feet in ancient time" (more commonly known as "Jerusalem"), ended by a short sample of the band's song "Dreamer".
The four orchestral suites (called ouvertures by their author), BWV 1066–1069 are four suites by Johann Sebastian Bach.
 The name "ouverture" refers only in part to the opening movement in the style of the French overture, in which a majestic opening section in relatively slow dotted-note rhythm in duple meter is followed by a fast fugal section, then rounded off with a short recapitulation of the opening music.
 More broadly, the term was used in Baroque Germany for a suite of dance-pieces in French Baroque style preceded by such an ouverture.
 This genre was extremely popular in Germany during Bach's day, and he showed far less interest in it than was usual: Robin Stowell writes that "Telemann's 135 surviving examples [represent] only a fraction of those he is known to have written"; Christoph Graupner left 85; and Johann Friedrich Fasch left almost 100.
 Bach did write several other ouverture (suites) for solo instruments, notably the Cello Suite no. 5, BWV 1011, which also exists in the autograph Lute Suite in G minor, BWV 995, the Keyboard Partita no. 4 in D, BWV 828, and the Overture in the French style, BWV 831 for keyboard.
 The two keyboard works are among the few Bach published, and he prepared the lute suite for a "Monsieur Schouster," presumably for a fee, so all three may attest to the form's popularity.
The Orchestral Suite in G minor, BWV 1070 is a work by an unknown composer.
 It is part of the Bach-Werke-Verzeichnis catalogue (BWV catalogue) of the works of J. S. Bach, and sometimes called the "Orchestral Suite No. 5", but was almost certainly not composed by him.
 It is more likely that the composer was W. F. Bach.
 It is a French suite with an overture and several dances, which has a similar structure with the 4 orchestral suites known to have been written by J. S. Bach.
 Different from those by J. S. Bach, however, the opening movement bears a different form, and the entire work has one movement not in the home key.
Water Music ("Wassermusik "), TWV 55:C3, is the common name of an orchestral suite by the German Baroque composer Georg Philipp Telemann, with the full title Hamburger Ebb' und Fluth (Hamburg ebb and flood).
 Telemann composed the piece in ten movements to celebrate the centennial anniversary of the in a performance on 6 April 1723.
 The suite draws upon Hamburg's geographical location as an important and successful port on the river Elbe while Telemann illustrates the piece with mythological water deities and tone painting giving the nautical theme added depth.
 The overture begins by representing the physical movement of the ocean, followed by several dance movements: first, the sleeping sea goddess Thetis, the mother of Achilles, who then awakes; the sea god Neptune in love; playful water nymphs known as Naiads; Neptune's son and sea messenger Triton joking; Aeolus, ruler of the winds; and Zephir, god of the west wind.
 Two final pieces follow, one depicting the tides of Hamburg and finally, its happy sailors.
Starstuff is an hour-long children's television program taped at WCAU-TV Studios on City Line Avenue in Bala Cynwyd, Pennsylvania.
 It was shown in the Philadelphia television market only.
 There was only one season of "Starstuff" with a total of 18 episodes airing on Saturday mornings.
 While it was first shown in 1980, it was rerun repeatedly throughout the next several years.
 The opening and closing music consisted of a melange of music from Gustav Holst's "The Planets" suite, movements four and six, Jupiter and Uranus.
Gustav Theodore Holst (born Gustavus Theodore von Holst; 21 September 1874 – 25 May 1934) was an English composer, arranger and teacher.
 Best known for his orchestral suite "The Planets", he composed a large number of other works across a range of genres, although none achieved comparable success.
 His distinctive compositional style was the product of many influences, Richard Wagner and Richard Strauss being most crucial early in his development.
 The subsequent inspiration of the English folksong revival of the early 20th century, and the example of such rising modern composers as Maurice Ravel, led Holst to develop and refine an individual style.

Question: Who was best known for his orchestral suite "The Planets" who had his music in the opening and closing of an hour-long children's television program
