Actually, they recorded from 1925 to 1991, with their last concerts together given at least up to 1981, where they played and recorded in Copenhagen. That includes the last year's as they played in places like Copenhagen and was recorded and released. The last years were AT LEAST 1991 because they came to our local fair and played in that year. Only Donald was alive at that time but he sang with his son in their concerts. Donald died in 1999 and idk how long he continued in concerts after 1991. Harry Mills died in 1982. Herbert died in 1989. Of course, John Mills Jr., the eldest brother, died in 1936 and was replaced by their father. They certainly were unsurpassed, as you said. 🙏

Agreed, the original is better, but this arrangement is good
