So in the end we all thoroughly enjoyed the concert. Lovely music. Lovely lighting. Lovely set design. TRQ behaved herself when the bell ringers showed up. She did have a tiny bone to pick, however, with some of the medieval costuming. Basically TRQ felt like she went to a Mo Tab concert and a production of "Spamelot" with dancing knights broke out.
But as I say it was a wee small (practically invisible!) bone, because you know what? Nothing says "Happy Christmas" like great Mormon Tabernacle Choir music.
And also dancing knights.
