Let us set aside all political opinions and rake "Richard Nixon, pianist" over the coals instead.
Here, performing (presumably on "The Tonight Show" with Jack Paar) is pianist Richard Nixon - from 1963, before he became President, performing an original composition - let us call it "I Know the G Major Arpeggio" - Paar took the trouble to have an orchestral accompaniment added to this lovely number. (G Major is a great key for string players, by the way.)
This will never be a political blog (follow me on Twitter for that - robertsonrick) - but there is a famous old one-liner that Nixon said about pianists - and it's here.
Now, there's gotta be a clip of Harry Truman out there somewhere - I recall reading that his favorite Chopin waltz was op. 42 in A flat...
