Looks like a V/V, V, I in F based on that limited info. The G7 is a secondary dominant. This sequence is probably preceded by Dm7 or D7 so it's just back cycling through the circle of 5ths. It's the same way you'd play over the B section of rhythm changes.

UPDATE I just listened to the song, it is definitely not Fm and it's not D minor )if that is what you meant to type) it is F (though I could see where confusion might arise between F and Dm). I only saw one lead sheet for this but it showed the song centered around F6 which is like Dm7/F so maybe that's from where the confusion arises.

Uh, oh Bob Carey I see an L-4 purchase on the horizon

Not specific to a 175 but I think wooden bridge makes for a more mellow, softer sound. And I think rosewood would be more in that direction than ebony. I'll bet Rich Severson had done this on multiple guitars and can describe it better.

I've used wireless and had no problems but unless there's some pressing need for it, I'd rather rely on cables.

James Champlin Go for it! Looking forward to your post when you start to get it under your fingers.  80-20 rule (finished not perfect)

I'm just a subscriber like you so I don't know anything about discounts but I 'd say don't buy a bunch of extra style packs right away. See how you use the program first then you can always add packs later. Maybe Wes Severson knows if there is some discount available.

I'd say go to the "Finger style" section of the library, do any introductory lessons then choose a song you like and already know cold. A Christmas song, Auld Lang Syne, an old standard, just pick something you could sing or hum all the way through the melody of the song and maybe could easily play the accompaniment. Then of those songs pick the one with the simplest harmony (least cord changes). I think that would give you the best introduction to the style.
