No matter how much musical theory you know, there's still new horizons to be learned. A week or two ago, someone here casually mentioned the augmented sixth chord and its function as a predominant. This is something that I never got up to in my formal music theory education, so off I went to Wikipedia (https://en.wikipedia.org/wiki/Augmented_sixth_chord). I'm now out of the rabbit hole (hi) and I'm seeing these chords _everywhere_.
I'm particularly pleased that I now understand the chord enharmonically marked "E7-5" in the bridge of this lounge arrangement of "A Nightingale Sang in Berkeley Square" that I like to play. It's a (French) augmented sixth on the ♭II of the scale, which resolves outwards to the I chord of the next verse.
So, thanks, Fedi.

Then literally a day later I realized that the chord leading into the chorus of "Swinging on a Star" (Yes I'm still working on the Furry Filk version of this) is an augmented sixth. https://www.e-chords.com/chords/bing-crosby/swinging-on-a-star
