There is a video on the Facebook page of the ICS Shanghai Live news agency (an English language news service in China) advertising their visit which was posted by Jimmy Riddle on Twitter (how do you find this stuff, Jimmy??? ) and which allowed me to find some of the other information.
While the translation on the official site describing Libera's role is imperfect, it has a song list.
- Peace. Do they mean "Deep Peace"? or "Rest in Peace"?
- When a Child is Born
- Ave Maria. Interesting, I wonder which one??? All seem to rely on an incredibly strong soloist with a very high range. There is the Libera in America version by Shubert, the version from New Dawn and Luminosa by Robert Prizeman, and the Caccini version from Visions.
- Stay With Me
- Amazing Grace
- Silent Night
- Be Still My Soul
What was totally unclear to me, and may be attributed to a lack of perseverance on my part in locating the information, is where exactly the performances will take place. I simply was unable to determine venues or dates. Perhaps someone else (Jimmy?) can help with this.
