Tolkien references appear later in the song's lyrics, including Mordor and Gollum.
Mine's a tale that can't be told,
My freedom I hold dear;
How years ago in days of old
When magic filled the air,
'Twas in the darkest depths of Mordor
I met a girl so fair.
But Gollum, and the evil one crept up
And slipped away with her.
The guitar's jangly introduction employs a classic Jimmy Page technique: using regular open chords superimposed higher on the fretboard.
There has been much doubt around Bonham's percussions in the background throughout the song, having regard to the particular resonance that it captures. There are no versions consistent in this respect: often mistaken for bongos, some said of a small plastic bin for waste played with the hands from the side of the bottom, others about the sticks on his drum kit vinyl seat pad, or even the soles of the shoes he wore during the recording session and so rhythmically beaten with his drum sticks; the book John Bonham: A Thunder of Drums reports instead of a hard case for guitar on which Bonham improvised percussion background with bare hands.
