A mainstay on Route 66, “The Museum Club” is closing its doors after Sunday. The bar and concert venue closed in September of 2017, but reopened three months later. Owners posted a message on Facebook Tuesday with the announcement. “The Museum Club” has been a mainstay in Flagstaff since 1931 as a taxidermy shop, trading post and a museum. “The Zoo” opened as a nightclub in 1936 at the end of prohibition. In 1963, Don Scott bought the club and turned it into a country music dance hall. Some of country music’s legendary performers have played the club over the years. Willie Nelson, Waylon Jennings, Blackhawk, Jo De Messina and more have played “The Zoo.” It was also known as a place where some of country’s headliners just stopped in and played a couple of songs while going from city to city on tour. It isn’t known if and when the business will reopen.
