As it happens, NASA – are we surprised? – have long before tested the combination of astronauts, musical instruments, and confined spaces.
When the Apollo 11 crew returned from the moon, they were swiftly locked inside the “Mobile Quarantine Facility”, a pressurised trailer designed to stop any lunar diseases escaping. (They were joined by a doctor and a technician, and presumably everyone carefully ignored the aircraft carrier they would have contaminated en route). After a couple of days, they were transferred to a set of living quarters with twelve other people, and spent the next three weeks waiting to see what happened.
(With impeccable logic, it was ruled that if any of them contracted inexplicable urgent medical problems, they would be transferred out of quarantine and into a hospital, which somewhat defeated the point…)
