Everett explained that he will take leave of all his duties with the Harvard band, his committees on campus and his work with students.
"I am not going to leave anyone out to dry here," Everett said. "Most things are in pretty good shape."
The announcement of Everett's leave of absence came as a surprise to many of the band members.
Trumpet player Reid M. Bolton '04, said his reaction was shock.
"I hadn't seen it coming," Bolton said, "We hope to see him again next year."
Everett said that it is difficult to look into the future, but that his primary concern is to take care of his medical concerns.
"In my 29 years I have never taken a vacation; I have never taken time off," Everett said, "So it's due."
