I think it is a good rule of thumb but perhaps too strict. I can see a couple of sentences being OK as long as they are short. Having backup explanations for dealing with technical difficulties can be good. I've heard Peter Yarrow talk about the meaning of Puff for a couple of minutes, playing the melody line the whole time while waiting for Noel to deal with a major retune (DC area can be hard on guitars for evening concerts).

That said, I want the banter to NOT be the main time or anywhere near.
