Episode 10 - Dexter Gordon intro?

OK, wondering if anybody can tell me what the tune that is that is playing when the narrator introduces Dexter Gordon in episode 10?

It's got a simple 5 note vamp playing on piano, then the sax and trumpet repeat it and then I assume it's Dexter soloing over it while the narrator talks about jazz work declining and how many left for Europe.

What's the tune? I would love to get my hand on it.

Thanks!
