It does. At least it did with me.
I was living in Ireland and attending secondary school at the time the song was released. I could never successfully associate the name of Oliver Cromwell with any of the other lyrics however. Being a shallow teenager, I wasn't inclined to chase down the background to ANY lyric as long as it went with a beat.
There weren't any other Olivers mentioned in history lessons though and as you might imagine Cromwell would've overshadowed them in the teaching of history at Irish National Schools anyway. I switched off of history altogether during secondary because of my mixed heritage and an inability to see what was taught in England and Ireland as being two sides to the same coin.
It's still a great song. If I had to perform it, I am not sure how I'd treat it though.
This seems like a plausible explanation for the title to Oliver's Army.
Can you provide some background to your statement please? I ask because I understood that the minister for labour from 1940 to '45 was Ernest Bevin. The only Oliver I found on a brief search of war ministers for the period was Oliver Lyttelton who was in office for the first year of the war as President of the Board of Trade. I found no mention of who was in charge of reserve occupations or who was in charge of same.
I am curious as my father was in a reserved occupation (Land Army). This has nothing to do with the topic at hand however so PM me if you like.
