(SOUNDBITE OF PERFORMANCE OF CHARLES BLAKE'S "IMPEACHMENT POLKA")
MARTIN: In 1868, President Andrew Johnson was being impeached. According to The Washington Post, a musician named Charles Blake saw an opportunity to cash in with this ditty called "Impeachment Polka." I'm not sure what about the polka explains the emotional ups and downs of impeachment. But, Charles Blake, you do you. Transcript provided by NPR, Copyright NPR.
