I can totally see how you could perform it that way, but personally I think it's a more interesting song if you don't. I suppose it depends whether you see it more as a Jolly Beggar song or a Begging I Will Go song. Textually it's a bit of both but if you turn everything into sexual innuendo you risk burying the latter element, whereas there's not much chance of burying the sexual subtext! Each to their own though. j
