Crosby, Stills, Nash & Young were scheduled for the Minneapolis Auditorium for May 24, 1970, with ticket prices at $5, $6, $7, and $10.

Hundred Flowers reported that Barry Knight and John Kome organized a boycott over the high prices, and the group cancelled, supposedly for other reasons.  They eventually rescheduled for July 9, with prices at $2, $4, $5.50, and $7.  In his autobiography, Wild Tales, Graham Nash says of the concerts on that tour:

As the dates tumbled on … the delicate CSNY fabric got even more frayed.  The electric portions of our show brought out the best and worst in us, particularly when it came to Stephen and Neil.  Their old competitive shit started frothing onstage.  The guitar breaks were like duels.  Ideally, those guys should have been inspiring each other, picking up on a riff and playing it right back.  Instead they were squaring off, trying to show each other up.  Stepping all over each other.  Afterward, in the dressing room, we’d almost have to separate them before they lunged at each other, ready to draw blood.
