In an interview with Tom Paxton - he said:
if you're writing a song satirizing a president who is an egregious liar, you don't bring the same vocabulary that you use with the seven-year-old boy's song.................... If I'm satirizing the president, I'll use a different box of tools. Each song has its own perfection that you strive for.

Tom - get writin' - there's a story with a lot of mileage unfolding!
