Trumpet instrumental

I cannot seem to find a clue anywhere, so I'm really hoping someone here can help me.

I can't recall if it's in any other episodes (as I'm finally getting a chance to go through all the episodes now that I have them) but in the very first episode of season 1, during some scenes there is a trumpet-y sounding instrumental track that's a little slower and reminds one of some of the Herb Alpert/Burt Bacharach songs from "Casino Royale". I cannot seem to find any info on this song, and it's driving me nuts because it's just so damn catchy!

Anyone have any leads on this particular track?

Many thanks
