Kernel says: "Look at some Muddy Waters video... he used a capo much of the time. Or watch some Rolling Stones video, Keef uses a capo
for many of his songs. So,
you should own a capo, a good one (I recommend Shubb). Simply try out my suggestion and make up your own
mind.
Here is a preliminary track I recorded last fall... I play it a lot faster than you do, but there's a kinship and a linkage over time and
distance. That's why I responded right away... I think it's so interesting that people so far apart in time and space might find common
ground with a song from even further back in time and whatever else we measure songs by these days. I call my version the "Bullfrog Blues..."

This track is just a preliminary work in progress... it's only one guitar and one voice.
I haven't decided what else might be added... lead guitar, harmonica, bass, drums
and harmony vocals for sure... But its so fascinating that you'd be working on something
so akin to this, and from another time and place.
