Todd's name had been circulating for some time with him filling in during recent weeks. From the clips I've seen, I think it will be a great fit.
Here's more from Gaither's release -
Todd has sung with the Settles Connection and can be heard in the background vocals on numerous recordings with artists whom you know and love. He comes highly recommended by fellow artists, university faculty, and many others who have had the privilege of working with him.
“First of all, I want to thank Mark Lowry and Michael English for giving us some really wonderful years and incredible recordings that will live on in gospel music history,” Bill states. “We knew when they left, we had big shoes to fill and, as I have said before, you never truly replace anyone. You have to create something new and unique. I have been putting voices together for a long, long time and never before have we considered more possibilities or auditioned so many incredible singers than we have during the past few months. This decision came down to finding a vocal range and texture that would offer just the right balance to the current mix of voices in the group. I could not be happier with this decision. Not only do we love the rich tones in Todd’s voice, he also happens to be a wonderful human being to be around. So not only have we gained a talented individual, we have gained a new friend. And very soon, I believe you will agree. Trust me. This is going to be good!”
