A British Invasion Reunion show came to Minneapolis on July 11, 1973.  From the blog of Jerry Fuentes:

The 1973 British Invasion tour promoted by Richard Nader. This tour was the first substantial nod to the budding nostalgia craze in America.  New York promoter Ron Delsener had the idea and contacted agent Danny Betesh about securing the talent.  Betesh had handled a number of acts back in the day, including Freddie and the Dreamers, who he still handled.  Unfortunately Freddie had a summer season booked in Great Yarmouth so he was unavailable.  Dave Clark turned down an offer but Peter Noone was interested and pretty soon a package was put together.  It was at that point that Delsener had to bow out.  He was dealing with the summer-long Shaeffer Music Festival in Central Park and had no time to devote to the tour.  Oldies producer Richard Nader stepped into the breach and promoted the tour.

An amazing reunion resulted from this tour and Peter Noone reunited with the Hermits.  In addition to Herman’s Hermits and Billy J. Kramer and the Dakotas, other bands on this tour included Gerry and the Pacemakers, The Searchers, and Wayne Fontana and the Mindbenders.  Billed as “The British are Coming Again,” the 21-date nationwide tour of the U.S. and Canada began on the East Coast and worked its way to the West before working their way back to the Midwest.

In addition to the tour, Nader arranged a booking with TV producer Burt Sugarman to do a British themed Midnight Special.  The filming took place on July 15th after the LA and San Francisco shows were cancelled and included all of the acts on the tour in addition to the Hollies and the Bee Gees, who hosted the show.  It aired on August 10, 1973.
