The program had the three Bach suites in the first half and the Debussy in the second but an announcer said the bergamesque and the middle Bach suite would be swapped - a good choice I think for more variety in sound character. While listening to the first Bach I was thinking that it would have been better on the harpsichord (I'm not a purist like some people) and have played (not very well) Bach on both the piano and the harpsichord. The other two Bach suites seemed perfect for the piano.
I'm glad she played nothing else - this was a nice ending to the concert. I think too many performers get carried away with the applause and try to play too much. Although I do remember the first concert I attended alone as a kid - it was Walter Gieseking and he played about 10 encores and it was really exciting to me.
This is not Hewitt, but Claude Debussy playing:
