Dwight, you have an FR-18.
Just keep changing the key until it is right.
It's not that many buttons to push

I'm not yet used to all the different patterns for getting notes out on the triple row. There's more options than a single row and I'm not yet where I can hear positions when someone is playing a triple row, unlike on a single row (sometimes).

i think we used to do that in C on the F row [2nd position]

but i have never heard chubby;s version

it was just where the guitarist wanted to sing it, or it was a compromise between his voice and available accordion keys i had at the time, and his guitar solos
