"Mr. Albert Hall is everything in appearance that a hypnotist should be," wrote the authors. "He is tall, dark, rather dreamily handsome, and was dressed in a casual outfit with a Byronic blouse of snow-white silk. At first glance he looked capable of leading us right into another world. But we were wrong again. For Mr. Hall couldn't have been more down-to-earth."
"He was always interested in the working of the mind and this was typical of him. He wanted to help people," said Ms. Janssen. "He was very gentle and sweet."
In 1970, Mr. Hall and his wife moved to Las Vegas, where she taught music and he worked as a real estate broker and a Roman Catholic church choirmaster and occasionally performed.
"I saw him perform in 'The Most Happy Fella' in Las Vegas, and he was brilliant. He was such a marvelous actor," said Ms. Janssen.
In 1987, Mr. Hall returned to Baltimore for a reunion concert of the Alamedians and continued to do so well into the 1990s.
"I met him when Mrs. B. started having reunion concerts and Albert and I did a duet. Our voices blended beautifully together," said Ms. Tormey, who had studied music with Mrs. Bowlsbey in the 1940s at the all-male City College while attending the all-female Eastern High School.
In 1995, Mr. Hall, Ms. Tormey and pianist Renaldo Reyes formed the Operetta Trio, which performed every two months.
After his wife's death in 2006, he settled in Stoneleigh and then Towson.
"We sang at all of the area retirement communities," said Ms. Tormey, who said Mr. Hall's last concert was Feb. 13 at Springwell, a Mount Washington senior-living community. "He even sang for the nurses at Gilchrist before he became unconscious."
Plans for a memorial service are incomplete.
In addition to Ms. Janssen and Ms. Tormey, Mr. Hall is survived by a grandson. His daughter, Marguerite Hansen, died in 2011.
