Hi, oombanjo - I changed the title of the thread to show that you're looking for banjo tab, but it appears that we don't have a MIDI for the conventional tune for "Sweet Sunny South." We have a "Bright Sunny South" MIDI, but it's a bit different. If somebody wants to e-mail it to me, I'll make sure it gets posted.
Oombanjo, check the crosslinks at the top of this thread for lyrics and background information.
Here's a link for somebody if they want to send me a MIDI.
