Please note: for this 90-minute video, image quality is much better on Youku than on YouTube. 
However, most videos on Youku are preceded by advertisements.
I have therefore chosen to embed one YouTube player as well as two Youku players on this page.
Here is the segment (t=33:33) in which Charlie Siem
plays Alexander's Ragtime Band  by Irving Berlin.
Here is the segment (t=59:56) in which Charlie Siem and
Nicola Benedetti play Nearer My God to Thee  by Lowell Mason
