Since 1997, the South African national anthem has been a hybrid song combining new English lyrics with extracts of the hymn 'Nkosi Sikelel' iAfrika' ("God Bless Africa") and 'Die Stem van Suid-Afrika' ("The Call of South Africa").
Konstantin Nikolayevich Podrevsky (Russian: Константин Николаевич Подревский , January 14, 1888, Turinsk, Tobolsk Governorate, Russian Empire, — February 4, 1930, Moscow, USSR) was a Russian Soviet poet of Polish origin on mother's side, a translator and lyricist, co-author of more than 150 popular songs of the 1920s, including "Dorogoi dlinnoyu" which he wrote with Boris Fomin.
"Book of Days" is a hit song released in two versions, both composed and recorded by Irish musician Enya.
 The original version, included on the 1991 album "Shepherd Moons," was sung in Irish Gaelic.
 The subsequent 1992 single version was bilingual, with new English lyrics; this version was recorded for Ron Howard's film "Far and Away," and scenes from the film feature in the video.
 The bilingual English-Irish version (2:56) replaced the original pure Gaelic version (2:34) on subsequent pressings of "Shepherd Moons" from mid-1992 onwards, making the original recording relatively rare.
Eh La Bas is a traditional New Orleans song.
 Originally it was sung with Creole lyrics but was later given French lyrics and the common title from the French lyrics.
 There have been numerous versions, including English lyrics that refer to both the Creole and French versions, and all employ a call and response.
Feodosy Petrovich Savinov (Russian: Феодо́сий Петро́вич Са́винов , born 1865, Totma, Vologda region, Imperial Russia, - died 1915, village Kuvshinovo, Vologda region, Imperial Russia) was Russian poet, best known for his poem "Rodnoye" (Close to Heart, 1885), part of which has been later turned into the lyrics of "Rodina", a popular tune, usually (and mistakenly) referred to as 'Russian folk song'.
"Doretta's Dream" is a 1987 single by Sarah Brightman.
 The song is based on the aria "Chi il bel sogno di Doretta" ("Doretta's Beautiful Dream") from Giacomo Puccini's opera "La Rondine".
 New English lyrics were written by Charles Hart.
"Those Were the Days" is a song credited to Gene Raskin, who put a new English lyric to the Russian romance song "Dorogoi dlinnoyu" ("Дорогой длинною", literally "By the long road"), composed by Boris Fomin (1900–1948) with words by the poet Konstantin Podrevsky.
 It deals with reminiscence upon youth and romantic idealism.
Electric Travel is the English EP album by South Korea-based indie rock and roll band The RockTigers.
 The album was released on April 30, 2011 through Stoneage Records and only available at live shows.
 Official release was on May 6, 2011.
 It features three songs re-worked from their previous full-length album Rock 'N' Roll Licence (Kimchibilly, Rockabilly Heaven, and Vengeance Is Mine) with new English lyrics and re-recording of the music along with three new songs (Electric Travel, Come Back, and Party In The Graveyard).
Asterix in Britain (French: Astérix chez les Bretons ) is a Belgian/French animated film released in 1986; the fifth Asterix feature film, and the last from Dargaud Films.
 It is based on the book of the same name.
 The theme song "The Lookout is Out" was performed by Cook da Books and was based on Plastic Bertrand's "Astérix est là" (the theme song from the previous film, "Asterix Versus Caesar") but with a slower tempo, played with acoustic guitars and brand new English lyrics.
"Soul Deep" is a song by Swedish pop music duo Roxette, released on 17 February 1987 by EMI as the third single from their debut album, "Pearls of Passion" (1986).
 The song was originally written by Per Gessle in Swedish, and was called "Dansar ner för ditt stup i rekordfart" ("Dancing Down for Your Draft in Record Speed"), but Gessle considered that title "too silly".
 He wrote new English lyrics and eventually the duo recorded it for their debut album.
 The single was only released in Sweden, Germany and Canada.
 It spent three consecutive weeks at number 18 on the Swedish Singles Chart, but failed to chart in the other two countries.
