In his 1974 book "Walking in New Orleans" John Broven notes that Archibald used to "delight in telling" that he was "born Leon T. Gross in 1912 on September 14 at 12.16 a.m., just off Plum and Hillary in New Orleans" which would make today his centenary, but 1916 appears to have been his correct year of birth. He died on 8th January, 1973.
His first record, and his only hit - produced by Dave Bartholomew in 1950 - 'Stack-a-Lee (Parts I & II)

He didn't record after 1952, but John Broven and others visited him at home in 1970 when "it was clear that times were not exactly good" but he sat down at his battered piano and gave as good a show as one could wish for in an informal session on a wet Saturday April morning"
