The accession of the King of France was legitimized by coronation ceremony performed with the Crown of Charlemagne at Notre-Dame de Reims.
 However, the person did not need to be crowned in order to be recognized as French monarch; the new king ascended the throne when the coffin of the previous monarch descended into the vault at Saint Denis Basilica, and the Duke of Uzes proclaimed "Le Roi est mort, vive le Roi"!
King Roger (Polish: "Król Roger" , Op.
 46) is an opera in three acts by Karol Szymanowski to a Polish libretto by the composer himself and Jarosław Iwaszkiewicz, the composer's cousin.
 The opera received its world premiere on 19 June 1926 at the Grand Theatre, Warsaw, with the cast including the composer's sister, the soprano Stanisława Korwin-Szymanowska, as Roxana.
"Le bon roi Dagobert" ("Good King Dagobert"), also called "Le roi Dagobert a mis sa culotte à l’envers", is an old French song featuring King Dagobert ("roi Dagobert") and Saint Eligius ("saint Éloi"), two historical people.
 The song was created in the 1750s and was intended to ridicule royalty.
 It was inspired by tales of debauchery of the life of Dagobert I.
Trance Atlantic Air Waves (also known as TAAW), is a side project from Enigma's Michael Cretu.
 He had previously worked with Jens Gad on Enigma's 1996 release "Le Roi Est Mort, Vive Le Roi!
" and they once again teamed up for this side project.
 Only one studio album was released, "The Energy of Sound", by Virgin Records.
 Most of the songs were cover versions but there were also three original songs.
Le Roi Est Mort, Vive Le Roi!
 (French for "The King Is Dead, Long Live The King! ")
 is the third studio album by the German musical project Enigma.
Le roi d'Ys ("The King of Ys") is an opera in three acts and five tableaux by the French composer Édouard Lalo, to a libretto by Édouard Blau, based on the old Breton legend of the drowned city of Ys.
 That city was, according to the legend, the capital of the kingdom of Cornouaille.
Le roi l'a dit ("The King Has Spoken") is an opéra comique in three acts by Léo Delibes to a French libretto by Edmond Gondinet.
 It is a lively comedy, remarkably requiring 14 singers – six men and eight women.
 The libretto had first been offered in 1871 to Offenbach; the title also went through various permutations ("Le Talon rouge", "Si le Roi le savait", "Le Roi le sait") before settling on its final name.
 The 1885 revival brought further modifications to the libretto.
Pasquale "Pascal" Mazzotti (16 December 1923 in Saint-Étienne-de-Baïgorry – 19 June 2002 in Saint-Ouen-l'Aumône) was a French actor who has appeared in film, television, and theater.
 He is known for having played a role in "Hibernatus" with Louis de Funès, as well as provided the voice of Le roi (The King) in the animated feature film, "Le Roi et l'oiseau" ("The King and the Mockingbird").
"The King is dead, long live The King!"
 (French: "Le roi est mort, vive le roi!"
 ; Spanish: "El rey ha muerto, ¡viva el rey!"
 ; Italian: "Il re è morto, lunga vita al re!"
 ; Portuguese: "O rei está morto, longa vida ao rei!" )
, or simply "long live the king!"
, is a traditional proclamation made following the accession of a new monarch in various countries.
 The seemingly contradictory phrase is used to simultaneously announce the death of the previous monarch and assure the public of continuity by saluting the new monarch.
