Nine Red Horsemen is in one of the lists of titles at this site, but I see no lyrics.

Here is what I recall:

I saw nine red horsemen
riding over the plain;
They all road as one man,
though I knew there were nine

(Chorus)

Ho-hilo-hilo-hilo-ho, ho-hilo-hilo-hilo-ho, ho-hilo-hilo-hilo-ho, ho-hilo-hilo-hilo-ho (i.e., 4 times)

(Other verses and choruses followed ... I can't recall any others)
