I participate on another forum where the guy who did the live sound for the inauguration posted. He was on the sound board during the performance and claimed that she performed live (vocals came from her mic). Maybe the Marine Band rep (who started the story) was told one thing and she did the other. He also mentioned that it is next to impossible to sync a taped singer to a live performing band in a live sound situation and make it sound good.
