Hi again Radriano, glad to see you're still around!
I too recall this version, I learnt it from the Ian Matthews (Southern Comfort) album Second Spring, but yes it's identical to the Farinas' version, which I'm guessing Ian would've been familiar with (he brought Reno Nevada to Fairport after all). But nowhere is there any explanation of the provenance of this version, and I too was always puzzled by the jumble, the apparent mix of WW2 and WW1 terminology. I admit, I tend to like singing this version in amongst bookending some of the verses from the "usual" version/s, it stops things from getting too predictable!
