In answer to this, Brucie, quite seriously.
For entry, you apply for a visa, and also a work permit, such as one would have to do to tour the USA, for example. I don't know whether the EU will now apply CITES, as the USA does, but if it does, you simply complete a 'carnet' to travel with your instrument(s).
As for cancelled gigs. Does she not think that the world-wide pandemic had/has something to do with gigs being cancelled? My band hasn't gigged for 11 months (a year next month), but then none of us were financially dependent on the income from them.
