SPY:

I recently saw the movie SPY with Melissa McCarthy and Jason Statham etc.
Mostly Jason Statham.
It was mostly Jason Statham and mostly the reason I needed to watch it.

It's actually a funny movie. It's not why we're here today though. It's the lush James Bond influenced opening number, "Who Can You Trust" that's sung with a very Shirley Bassey approach. I just assumed it was K.D. Lang. So I went looking for it using (K.D. Lang spy theme) with no results. Then searched (Spy the movie theme) and came up with Ivy Levan.

Wow.
