I saw one of the tours and I know for sure Tommy James and the Shondells were on it as well as Paul Revere and the Raiders. Can't remember the others!
I remember the tours of the late 1950s. Many of the stars of that era travelled with the show. Jackie Wilson, Clyde McPhatter, The Jordan Brothers and many of the one hit wonders of that era travelled with the show.
I saw the Supremes, Lou Christie, Manhattan Transfer and Gene Pitney for sure. This was circa 1964. I have read that The Shirelles, the Crystals, Johnny Tillotson and Brian Hyland were also on this tour.
