"Perhaps the term "walkabout" does derive from Aboriginal Australia, but nowadays it's used widely here to describe someone out and about to visit a place and meet folks, yes?" (me)..."No, only by morons who watch Australian soap operas. (apologies to all morons)" (Smokey) and Howard...I'm no monarchist but when the Queen, e.g., goes out to meet people the media here nowadays nearly always describe it as a "walkabout".
And as for "I wonder what the Authorities would call you?"...officially I'm a dual national with two passports.

Stigweard - which fiddle?...

"PLAYING THE FIDDLE?

There are many different fiddles from many different lands – for example, the Chinese erhu fiddle, the Norwegian hardanger fiddle and, the one most in the West now play, the Italian fiddle/violin" (here).

Volgadon - that's roughly my understanding and also the one in the 1970s movie "Walkabout".
