This particular blog has nothing to do with the 1965 Twins other than it took place in Met Stadium in 1965. I missed all the hullabaloo as I had just reported to U.S. Navy boot camp at the Great Lakes Naval Training Center to begin my 3+ year hitch.
On August 21, 1965, the Beatles traveled to Minneapolis Minnesota for a show at Metropolitan Stadium as the sixth stop along their 1965 North American Tour. Tickets were $2.50, $3.50, $4.50 and $5.50. The group received a guarantee of $50,000 and an additional 65 percent of sales above 18,500 tickets. 30,000 tickets were sold.
There are a number of good articles about the Beetles visit and I will try to provide you with some of the links.
