There was a Capitol Tavern in St. Paul in 1949 that had music, but I have no location.  Unfortunately I didn’t note the source of this factoid, but it probably came from Joined at the Hip.

Now we have a postcard of the Capitol Bar, located at Rice Street and University Ave., and I will post it here and guess that they may be one and the same.  But no guarantees.  St. Paul is the State Capitol, you know.
