Mark Russell was an American political satirist and comedian.
He is best known for his series of semimonthly comedy specials on
PBS television between 1975 and 2004. His routines were a mix of
political stand-up humor covering current events and musical parodies
in which he accompanied himself on his trademark American flag-themed piano.

He was a funny guy, and he will be missed.
Mark was 90 years old. Well done, sir.

R.I.P., Mark, and thanks.
