I don't know if this is relevent, but the only times I've heard "Virginny" sung, the line
"More fitting to serve George our King;
( or "More fitting to serve Victoria our Queen;")
it's been replaced by
"More fitted to serve than to die on a string"
I don't know if it is a "modern" substitution, but it is certainly in keeping with the use of Transportation as an altrnative to execution.
