Excerpt from American Songwriter Interview, by David Friedman. I didn't see it the first time around.

“Songbird,” the disc’s first single, is one of its most beautiful moments.
WN: Thank you. I really love the arrangement on it. Fleetwood Mac had a great record on that. I didn’t know how my version of it would sound, but Ryan’s band, The Cardinals, are really good. These guys could play anything. We were doing [Harlan Howard's] “Yours Love,” and I don’t think the steel player had heard it before, so I said, “Well, just play, ‘Waltz Across Texas’…it’ll work fine [laughs].” So when you hear that song, if you hear “Waltz Across Texas,” that’s how I got there.
