The first recordings were made on wax, and wax for a decade or more meant to record some music, and one could according have waxed lyrics. In the stories about knights in armor, they were said frequentluy to have waxed wroth. So I think it was Groucho Marx who made a joke about Roth getting tired of being waxed, and striking back.

He's waxing wroth! "
" Well, why don't you have Roth wax him for a change? "
~ Groucho Marx
