В сердце моём: История песни из "Тарзана" V serdtse moyom: Istoriya pesni iz "Tarzana"

Song by Phil Collins
the 1930 German film

A demo version with Collins playing piano and singing is featured as a bonus on the 2 DVD Special Edition of Tarzan, along with "I Will Follow", "Celebration", "6/8 Demo" and "Rhythm Piece" which became "Strangers Like Me", "Son of Man" and "Trashin' the Camp". "6/8 Demo" was not featured in the movie. The music video for the song was directed by Kevin Godley. Phil Collins also recorded the song in French ("Toujours dans mon cœur"), German ("Dir gehört mein Herz"), Italian ("Sei dentro me") and Spanish ("En mi corazón vivirás") aside from his native English. A version of the single performed by him with Glenn Close also appears on the soundtrack.

Phil Collins was originally hired by Disney in 1995 as a songwriter, but was chosen because he was a drummer at first and given his history as a drummer for the rock band Genesis, Collins appealed to the Disney production crew, who "wanted a strong jungle beat to accompany Tarzan's adventures". Early into production, directors Kevin Lima and Chris Buck decided not to follow Disney's musical tradition by having the characters sing and instead, Phil Collins perform the songs in the film serving as the narrator. The choice of Collins, a popular and well established adult contemporary artist, led his ability to write and record the five original songs. This "ballad" is one of the original songs he wrote for the film, and he ended up also performing this song as well. The song, originally written for his daughter Lily, who was ten years old at the time, was called "Lullaby", is used in a scene when Tarzan's adoptive gorilla mother Kala sings that her baby should stop crying because she will protect him and keep him safe and warm. She says everything will be fine and she tells him that "you will be in my heart always". The song is about "how love is a bond that cannot be broken". In the movie, the song ends on the first verse, the full version of the song on the soundtrack album notes that others don't understand why a mother and child who are so different can love each other. When destiny calls, the child is told he must be strong even if the parent is not with him. The song is one of only two songs within Disney's Tarzan to have a part performed by an actual character (the other being "Trashin' the Camp" which the character's role in the song can be classified as scat singing). The rest of the songs were performed by Collins himself and overlaid into the movie. The full song is finally played all together during the end credits. In the 2006 stage version, the song is performed by Kala with the ensemble, while a reprise is performed by Merle Dandridge as Kala and Daniel Manche as Young Tarzan when the latter "decides to join the human world".

The entire Tarzan soundtrack, including "You'll Be in My Heart", was also performed by Phil Collins in various other languages besides his native English, namely German, French, Spanish and Italian. Most dubbings played the full English version of the song by Collins at the end credits but it has six versions in other languages and includes his full Spanish version that played for the European and Latin American dubbing, which marks Phil Collins' only appearance on Billboards Hot Latin Tracks, the song charting at number 32.

Then SM Rookies member Donghyuck, who later debut as a member of boy group NCT under the stage name Haechan performed the Korean song on the Disney Channel Korea show Mickey Mouse Club in 2015.
