Scene: Lost in Emyn Muil

CR-TTT Track: Lost in Emyn Muil; 1-3

The voices are very soft and it is difficult to discern the exact words/syllables being sung.

Scene: Pippin tears off his Elven Brooch

CR-TTT Track: Uglúk’s Warriors; 1-5

[1:34] wacode

Although the same basic melody is in the movie, the singing is not. It matches with the music heard as Pippin is tearing at his brooch and spits it on the ground until the Uruk foot steps on it and the scene switches to our first glimpse of the Three Hunters. The source text is The Missing (per the AS-TTT) but the specific words used are harder to determine.
