Which producer's son supplies the child's spoken prayer in Metallica's "Enter Sandman"?

Bob Rock's son supplies the child's spoken prayer in Metallica's Enter Sandman. His voice appears during the bedtime-prayer section of the song.

The spoken passage uses the traditional prayer beginning “Now I lay me down to sleep,” placing familiar childhood language inside a darker song about nightmares and fear. That contrast became one of the track's most memorable details.

Bob Rock produced The Black Album, and the recording involved close collaboration between the producer and the band. The child's voice is an additional performance credit rather than a contribution from one of Metallica's four members.

The detail is often misremembered because the song is strongly associated with James Hetfield's vocals, Kirk Hammett's guitar riff, and Lars Ulrich's drums. Those musicians perform the main track, but the spoken child part came from Rock's family.
