I wondered the same thing when I saw Dwight Hudson do it back in the 70s (at 1:46):
Dwight Hudson: 1977-1979
In 1975, when he was a junior in high school, he was introduced to a prominent baton instructor, Mrs. Dee Felz of Columbus, Ohio, a former head majorette from Northwestern University (1956). Mrs. Felz gave Hudson the necessary technical training and the confidence to make him a champion. He was well rehearsed and gave numerous performances, competing in events which enriched his experience. In his last years high school Hudson was a well-known star, a veteran of many band contests, parades and shows around central Ohio.
Additional help and encouragement from drum majors Ohio State did not come until his senior year in high school. The OSU band was aware of his talents, but so were other universities; Michigan, Northwestern, University of Southern California, and many Ohio colleges offered scholarships plus “extras" if he would enroll with them. Ohio State offered him nothing . . . nothing but the finest band with the best reputation for drum majors in the country.
Hudson's father, an employee at The Ohio State University, had for many years taken him to OSUMB rehearsals. Here he had acquired aspirations to lead the band. His personal letter written to the band director when he was in the fifth grade clearly states his intentions. Perhaps the reason that Hudson came to Ohio State was that he wanted to honor his dying mother's wish. She had hoped that some day he might lead the band at Ohio State.
The accomplishments of Hudson are many. For three years he served the band with distinction. He was voted the Most Inspirational Bandsman of the OSUMB in 1978. His showmanship and baton tricks surpassed description. If one were to single out a small fraction of his greatness, it would have been his timing. He had the ability to think ahead in music as much as two measures, throw the baton high in the air, execute one of his gymnastic movements, and recover the stick on the last musical note, winding up with a fantastic gesture and facial expression that told it all.
Because of his extreme popularity, Dr. Droste allowed Hudson to return for a third and final year in 1979, breaking the unwritten two-year rule. At the same time, Droste created the drum major squad, a group of prospective drum majors who trained during fall quarter.
Hudson received many standing ovations during his tenure as drum major. However, none surpassed the tremendous ovation he received following his farewell performance in 1979.
