Quite a mystery solved! Kostas Trogadis was named on a Greek Blog Kostas Logiatis, while the Logiadis known is a conductor,
of a Jackie Callas concert. Mr. Peppas wrote to Robert Schlesinger that he found the announcement for that 1957 Jackie Callas concert,
and the tenor was Kostas Trogadis, born in Lamia in 1909, at the Greek Opera Theater Athens from 1939, a leading tenor there
in the 1940s and 1950s.
