I'll try to find Mel Bay's book somewhere on the internet now I have the need to read it hahaha. For me the best part of the song if I had to choose would be the chorus (it takes love over gold...) I love the Bb C Ebmaj7 Gm7 Bb6 A7#5 Dm7 ending on the huge F#7#9/C# C13 and the melody "walking" into C#/B
Although what I enjoy the most is playing the lead parts fills and solos like in Pavel's video it's incredibly satisfying to play the whole thing!
Also take a look at Mickey Baker's Jazz Guitar book, especially volume 1. It's not a great book. It's old, and the teaching method is kind of questionable ha-ha But many people have used it over the years, though, including Richard Bennett, and I think also Mark. You'll learn many lovely chords and progressions, and I'm pretty sure I've heard several of those progressions in Mark's music over the years. It's available online in PDF format.
