Jack Benny’s most famous Irish Tenor, Dennis Day was born on May 21st, 1916 in New York City and raised in the Throggs Neck section of The Bronx.

Day graduated from Cathedral Preparatory Seminary and attended Manhattan College, where he sang in the glee club. Eventually he made his way to radio. Dennis Day made his Benny debut on October 8th, 1939. During World War II, Day enlisted in the Navy. He made his return on the St. Patrick’s Day episode, March 17th, 1946.

For the remainder of the season, the Jack Benny cast was reunited in its classic 1940s incarnation. It was the last season before Phil Harris took over the Fitch Bandwagon with his wife Alice Faye. Because the program aired immediately after Jack’s, Phil could generally only take part in the first half of Jack’s show before rushing over to broadcast his own.

Beginning that October, Dennis Day too would get his own show on NBC.
