Well, I'm glad I found this thread and the above link. It confirms something I had always heard about Mac Wiseman -- that he was classically trained. Actually, I had assumed that he had had classical voice training, though only a stint at conservatory is mentioned in the bio. But this may explain something alse I have heard about him -- that he never uses a capo (B-flat? No problem.) I love a lot of his work, particularly Can't You Hear Me Callin' and other stunning duets with Monroe. I never did care for the sappy little minor-key coda he added to Jimmie Brown the Newsboy. Give me Lester Flatt and Earl's lovely guitar breaks on that one.
