Tom S,
Have you ever seen or played an electric accordian? I inherited one from my mother-in-law who used to play it in a dance band. It's built on the order of a keyboard with keys for the right hand, buttons for the left hand, and a bar-like pedal you control with your right foot. It's LOUD and when I play it in the summer time, the dogs come running to sit in front of the screen door and howl!! Kinda fun though, but I don't play the thing when there is anyone but the grandkids and the dogs around to hear me. It isn't much different than chording on the piano, but the dogs don't participate when I do that. Although they have joined in when I try the fiddle, guitar or banjo - I'm equally awful on all three.
I'm choir director for our little country church and love to sing when someone else plays the piano, especially Southern Gospel stuff. My mother's family had their own hillbilly group that had a jam season everytime they got together. Just love that oldtime cowboy music!!
