Hi Night Owl,
Here's the info on that cassette:
Autoharps (Ron Wall & Mark Howard) on the Cumberland label.
Distributed in the U.S. by Benson Music Group Inc., 365 Great Circle Road, Nashville, TN, 37228.
In Canada, by R.G. Mitchell Family Books, 565 Gordon Baker Road, Willowdale, ON, M2H 2W2
As mentioned in the earlier posting, it's about 10 years old (if I'm reading the Roman numerals right), so I'm not sure if any of that is still current.
cheers.....ddw
