A shakey but interesting video, of Susy Bogguss — a Country female singer — on stage in Pueblo (Colorado), with a guest musician. The guest is a funny fellow, Brent Ritter, local vocalist of the Pueblo Municipal Band, and serious nose flute player.
I don't see well, but I guess he does not play a plastic Humanatone, but probably a vintage metal one. You can see from 1'15" that the singer has to stop singing because she laughs. Cool nose flute solo from 2'56".
