A reader writes, "Patrick Costello – you have posted about his work as an open source banjo teacher several times – is having surgery this Thursday at Johns Hopkins to install a BAHA implant so he can continue teaching."
Patrick is the king of open-source banjo teaching, a public-spirited saint who teaches and produces teaching materials on a free/open basis. The BAHA is an implanted hearing aid that will be fitted as part of a surgery to relieve an excruciating bone infection.
Good luck, Patrick!
