P.S. A couple people asked for more info on Suzi and John, who are on my CD(s). I've joked for many years that I'm the least famous person on the project.
Suzi Stern is one of the most accomplished singers in any genre of her generation. She has tons of recording credits, but is probably best known in the jazz world for her work with Denny Zeitlin. Suzi wrote the lyric for Denny's standard Quiet Now, which has been recorded by many a person. Her voice is not to be believed--I have worked with scores (pun maybe intended) of incredible vocalists in my career, but Suzi has the next to impossible to find combination of flawless technique coupled with amazing heart and soul.
John Stowell is probably one of the two or three most respected jazz guitarists of the last 50 years or so. I'm sure BK's close personal friend Grant Geissman either knows John or has heard of him. John is frequently called his generation's Jim Hall (in fact, I believe Jim himself called him that, LOL). John first became famous for his many duet albums with bassist David Friesen (Dyan Cannon's brother). Dave and John won many-a Downbeat critics poll. John later was part of the group that Paul Horn took to Russia--they were the first western jazz group to play behind the Iron Curtain, back in the days when it was still detente.

John has, like Suzi, recorded with so many people it's hard to list them all: Lionel Hampton, Claudio Roditi, Dom um Romao, on and on. John is famous among guitar players for the unusual way he holds his guitar when he plays: he holds it vertically, so that the neck is pointing more or less straight up.
