Eleanor Rigby sounds good but the words don't really tell much of a story.

I think that's about the strangest statement I've come across in a long time.

I remember Dan Keding, I think it was, in a storytelling worskshop saying how the key to oral storytelling is knowing what to leave out, so that people can fill in the spaces and the details with stuff from their own lives and from the stories they've come across. I think Eleanor Rigby is a superb example of that.

I'd say there are any number of Beatles songs that work brilliantly in pub sessions. And which sound just fine with an acoustic accompaniment.

If they work better for you with a bit added or a bit taken away, fair enough. If you find other people agree with that, fairer still. Not that likely maybe, but the folk process can always throw up surprises about things like that.
