A question regarding FM in other countries

[He's So Unusual]

Does anyone know how successful Fleetwood Mac are in Denmark? I can't find a lot of chart info for that country. According to Setlist.fm they've played a handful of shows there since the 1960s, the last one in 2013. Did their last two concerts sell out? Is there music played on the radio?

Why haven't they played any shows in Japan and Italy since the 1990s? They toured Japan three times between 1977 and 1990. It seems strange that they just stopped.

Why have they never toured South America? I'm not sure how well their albums charted there. Surely they're at a point now where they can play a few successful shows there.
