Monday, January 15, 1973.  I was a 19-year-old college sophomore.  In the evening, accompanied by my sister and piano teacher,  I attended a piano recital at the Academy of Music in Philadelphia given by the 87-year-old master pianist, Arthur Rubinstein.  I remember that he opened the program with the Bach Chaconne, arranged by Ferruccio Busoni.  I vaguely recall that Rubinstein played a piece by Liszt as an encore.
