Single generation of transformation group algebras

We prove that $C(X)⋊\mathrm{\Gamma }$ is singly generated whenever $\mathrm{\Gamma }$ is a finitely generated discrete amenable group and its action on the nonempty compact metrizable space $X$ is free, minimal, and has the uniform Rokhlin property and Cuntz comparison of open sets. In particular, every free minimal ${\mathbb{Z}}^d$-crossed product with metrizable underlying space is singly generated.
