I sent an e-mail to the owner of Folk Era and asked if he wanted to answer the question above.

My favorite records are the Ian and Sylvia releases where the stereo separation for each voice was reallly clear. I sure wish other recordings, especially the great Nanci G duet records, had the two parts clearer.

On a good day, I can sing either Sylvia's or Ian's parts on a lot of their greats - of course, not at the same time -- or as good!!
