Hey Tim;
No I don't remeber any thing like you described, re. the Zulu Warrior.....but I don't think I'd mine watching!!!! ;-D
I looked to see if there was anything about Roman engineer(s), and sorry to say I didn't find any thing. I even lookes up in train songs, (in my books), and nothing. Sorry. Hope ya find it somewhere..
But If It's any interest to you or anyone else out there, I found some other songs, (again this is just the tip of that proverbial iceberg), that may be of interest:
Cousin Jedediah, Mule Skinner Blues, Clementine, O Susanna, Marines' Hymn, Aloha Oe, Santa Lucia, Bones, Jeanie with the Light Brown Hair, Yodeling Song, (Oh I'll have to find that post... I remember someone wanting yodel songs)
anyway there's hundreds more I'm gonna have to figure a way to post them all.... "OH--DICK!!!!!", gonna have to get in touch with him too! Happy hunting to all! Becky
