There is not, though. No native speaker of English, which the newspaper of record in Houston, Texas, might be forgiven for assuming make up its primary readership, would ever assume that anything described as a "one-man show" must have a woman hidden away doing all of the behind-the-scenes work. The idiom means "the work of a single person," and that's it. Nothing else.
