A D Magazine Guesstigation: Is Rhett Miller Yodeling for Olive Garden?

For the past few days, I’ve seen an Olive Garden commercial whose never-ending pasta bowl jingle is sung by a fellow who sounds exactly like Rhett Miller. I finally remembered to ask the internet about this, and people certainly are chattering about it, but no response from the crooner himself. Nor can I find the commercial online. Anyone else notice this?
