The John Conte Show was heard on ABC Radio on weekdays. In the newspaper listing it was usually just listed as “John Conte” or “John Conte Show,” with no other information given. However, this one small article was located in the August 1, 1954, edition of European Stars and Stripes, Darmstadt, Hesse, Germany.
On August 3, the first Tuesday after this date, the program Songs of the Islands is listed in this time slot on the Armed Forces Network (AFN) schedule. But, on the August 10th AFN schedule, the Conte show is listed in this time slot. So, it is likely that the Stewart appearance was on August 10, 1954.
The show is not available, so the exact nature of Stewart’s appearance isn’t known.
