THE JUDDS are no more. The popular mother-daughter duo, known as much for their 18 No. 1 country-and-western songs as for the fact that it's fun trying to tell them apart, staged an emotional farewell concert in Tennessee last week, a pay-per-view extravaganza that capped a yearlong 118-city farewell tour. Mother Naomi and daughter Wynonna (or is it the other way around?) are ending their professional partnership because of Naomi's battle with chronic hepatitis, but Wynonna will embark on a solo singing career, with occasional help from Mom.
