From a Washington Post obit by Bart Barnes headlined “Mark Russell, political satirist with a star-spangled piano, dies at 90”:

Mark Russell, Washington’s social-political satirist and stand-up comic who spoofed, teased and laughed at celebrities, politicians, politics and popular culture for more than 50 years from behind his star-spangled piano, died March 30 at his home in D.C.

From the waning years of Dwight D. Eisenhower’s administration through the presidencies of 10 succeeding chief executives, Mr. Russell poked fun at the foibles and flaws of the well-known, the pompous and the powerful in monologues replete with pithy one-liners and musical ditties. He called himself “a political cartoonist for the blind.”
