List of All Tags Used on a Board or Blog, Regardless of Activity

I can get a list of the tags receiving activity in a node for a chosen date range, but management would like a list of all the tags applied, regardless of whether they were clicked. Community Analytics will give me the activity report, but I'm not looking for activity, just existence. Any ideas?

PS I'm not great at writing queries from the browser address line, but I figure that's where this will end.
