I remember Mockingbird Hill done by Peggy Lee & by Les Paul & Mary Ford. It was on the "Hit Parade" for week after week in 1950. btw: it was not a time of peace. We were imeshed in the Korean Conflict, McCarthy was in full sway, the Rosenbergs were on trial.
Not a peaceful time at all. A wonderful song then and my music students like it very much now.
