From the Grand Terrace, Hines and his band broadcast on "open mikes" over many years, sometimes seven nights a week, coast-to-coast across America – Chicago being well placed to deal with live broadcasting across time zones in the United States. The Hines band became the most broadcast band in America. Among the listeners were a young Nat King Cole and Jay McShann in Kansas City, who said his "real education came from Earl Hines. When 'Fatha' went off the air, I went to bed." Hines's most significant "student" was Art Tatum.
