Here is a video signaled to our attention by JobTePas. Jan Ruijg plays a very special nose flute : a metal early-Humanatone shaped flute, stuck to the handle of a crutch !
The crutch itself is drilled with holes, like a recorder, but it seems to me they are not functional, just theatrical (how can them be, since the the air does not enter the crutch?)
Another interesting video by Jan Ruijg here :
