Rick, The Carol Lee singers have been the Opry back up singers since approx 1974. The group was Carole Lee as lead with a set of unique hand signals to guide the rest of the group as to when they will sing words or "ooh and aah" or when to listen. The bass singer was Herman Harper who for 13 years was bass singer for the Oak Ridge Boys. Norah Lee Allen is the alto singer, and is married to Duane Allen of The Oaks, and last but not least is Dennis McCall who sings tenor. Dennis is married to an Ottawa girl and is often up in Ontario. Herman Harper passed away a few years ago and there have been several base singers over these last years. This is probably more than you ever wanted to know Rick but they are an institution at The Opry Shug (Dizzies other half)
