Back in the States, in February 1983, Hall appeared on the bill of the 100th birthday celebration for composer Eubie Blake held at the Shubert Theater, New York. Unfortunately, Blake was recovering from pneumonia at the time so could not attend the event but with the aid of a special telephone hook-up to his home in Brooklyn he was able to listen to the entire two-hour show.

Q: Passage: Born in Nereju, Vrancea County, he attended a polytechnic institute in Germany and became an engineer. Hired by the state railway carrier Caile Ferate Romane in 1911, he rose through the ranks from maintenance work at Adjud and Barlad to inspector at Galati in 1919 to deputy department head (1931) and department head (1932), before becoming deputy general director in 1935 and general director in 1936.

The final phase of his ministerial service lasted from September 4 to 14, from the time Ion Antonescu assumed power to the establishment of the National Legionary State. Arrested by the communist regime in May 1950, he died at Sighet prison five months later. His wife Ecaterina was arrested in 1952.

Q: Passage: The tercentenary was kicked off in Imperial Capital St. Petersburg on a rainy February morning. The event had been on everyones' lips for several weeks leading up the actual date, and dignitaries from the whole of the Empire had gathered in the capital's grand hotels: princes from the Baltic and Poland, high-priests from Armenia and Georgia in the Caucasus, and mullahs and tribal chiefs from Central Asia alongside the Khan of Khiva and the Emir of Bukhara. Additionally there was a large group of visitors from the provinces and workers, which left the usual well-dressed promenaders of the Winter Palace outnumbered. The city was bustling with these visitors, and Nevsky Prospect experienced the worst traffic jams in history, due to the converging of cars, carriages and trams. The streets themselves were decorated in the Imperial colors of blue, red and white, statues were dressed up with ribbons and garlands, and portraits of the line of Tsars going all the way back to the Romanov dynasty's founder Michael were hung up on the facades of banks and stores. Over tram lines were chains of light hung up, which spelled out 'God Save the Tsar' or portrayed the Romanov double-headed eagle with '16131913' spelled out underneath it. For many of the provincial visitors this was their first sight of electric light, and they stood in wonder of the 'columns, arcs and obelisks of light'.
