This is the Midnight In Paris cover of Let’s Do It by Cole Porter. It’s sung by Leslie Hutchinson. I couldn’t find the original Cole Porter version on Youtube, but this is a really great cover, anyways. The original 1928 Cole Porter version is also available on Spotify for free.
One of my favorite songs ever. Unfortunately, it’s also one of the catchiest and most awkward songs to sing in public. Behind Bessie Smith’s I Need A Little Sugar In My Bowl.
