Nicks told VH1 that "it's very serious, it's a song that I wrote about Walter Reed that's called 'Soldier's Angel.' So Lindsey came in and played guitar. It's just Lindsey and me. It's very Buckingham Nicks and I think that it's going to be a very serious and important song to the world and I think it's a very serious and important song for Lindsey Buckingham and Stevie Nicks because it sounds like Buckingham Nicks. Because it is."
The smoky voiced singer also said about Buckingham that "it's just him playing guitar and me and he sings with me on the choruses. And it's ominous. It's an ominous song and his voice lent even more ominousity to the whole thing. So I think the world will be really knocked back when they hear 'Soldier's Angel' and I'm really excited for them to hear that."
