Well as usual I learned a "Street" version that isn't quite the same.... we sang this at GWU in the early 60's and I still sing it around the house sometimes....

I don't want to join the Army,
I don't want to go to war
I just want to hang around
In London by the Underground
Living off the earnings of a high-class lady [LIgh-dy]!

I don't want to join the Navy, ["NIgh-vy"]
I don't want to sail away
I just want to hang around
In London by the Underground
And Fornicate me bloomin' life away!
