FILE - In this March 21, 1969 file photo, President Richard Nixon plays the piano as first lady Pat Nixon, former President Harry Truman and his wife Bess watch at the Truman Library in Independence, Mo. This is the piano Truman used to play in the White House and was presented to him as a gift by Nixon. Through the years, commanders-in-chief have turned musicians-in-chief, with varying results.
