I am a music engineer and producer and there is no way to get those vocals from the microphones they use or in those placements. I googled this because it is such a mockery music and live performance that it really disgusts me. Someone mentioned Madonna, and I come to think of Michael Jackson as well, but these are global first class stars that people want to see in person and dancing. Their music and vocals became so engineered later on in their career that it would be almost impossible for them to sing live, especially with their dancing coriography. HOWEVER, this Celtic Woman bolony has women just standing on stage lip syncing songs that they did not write. WHY?! The world is full of talented people that could perform these songs live, which IS the reason people go to see a live performance. They call it a CONCERT, and that is FRAUD and it should be tried in court. Some people said their children enjoy it, but children enjoy puppets. This whole production is an insult to real musicians, singers, and performers and extra insulting to have Irish people patronising Americans. If you admire this then you do not have any real appreciation for art and you have been conned. PBS should pull this off of the air immediatly and get back to allowing talent back on the airwaves.
