Scattering amplitudes in gauge theory and gravity are related, to all orders of

perturbation theory, by a map known as the BCJ double copy. This suggests

that there is a link between classical backgrounds in these theories. In this

talk, I will propose that a general class of solutions of Abelian gauge theory

double copy to Einstein gravity, namely the case of stationary Kerr-Schild

metrics. Examples include the Schwarzschild and Kerr black holes. I will also

discuss the double-copy map between self-dual solutions of Einstein gravity

and Yang-Mills theory, and explain how this map fits into the Kerr-Schild

framework.
