Thanks, Lisa, I agree that C and F make the most sense to me. My tuning is CGG and having the C and F chords in both keys is a great way to keep this simple. It will be a lively song for a jam on death and I want to start in C with the verse on melody string only, then across the strings for the chorus, ending on C for a measure, then Bb (suggested by Jan Potts since it's in F) for a measure and then F for a measure (or those two, Bb and F, maybe only half a measure each), before starting the chorus on an F chord for the chorus a second time, but in F.
It also gives me an ending with a measure of F, then half each of Bb and F.
What I really love about your suggestion is the link! I plan to prowl that site like crazy. I am at an awkward stage with the need for either arrangements and/or learning how to do my own. There's even a bit of a story to it. (My playing sometimes uses the excuse of "Now you know why I am a storyteller and not a musician."). I now handle the rights to the songs and arrangements of my late aunt, Norma Andersen. Her musical world was Barbershop, but I bet she's approving my own musical journey. Thanks for nudging me a bit further.
