Canned Heat was billed as "Stars of Woodstock & Kickapoo Creek Rock Festivals" and several ads included a picture of the traffic jam along the road to Woodstock while mentioning "10 acres of free parking" would be available. These ads, which ran in newspapers across northern and central Illinois, made it seem as though this would be an outdoor festival similar in size and scope to those earlier events.
The promotional campaign to cast the Canned Heat concert as a "gigantic rock festival" may not have fooled any concertgoers but it was enough to put fear in the minds of city officials and some residents living on the west end of Peru. In the weeks before the concert there were several attempts to block the event.
It didn't help the that the local papers had recently reported on the drug-use and perceived lawlessness of the Kickapoo Creek rock festival which had occurred just a few months earlier in central Illinois. One Illinois legislator referred to that event as "a muddy and obscene haven for dope-users and flower children."
Peru citizens expressed fear that their town would be overrun by a similar crowd. Nearby taverns and local businesses such as the Igloo Drive-In (still in business) said they would close as a precaution.
The situation took a turn for the worse when alderman William Roth referred to potential attendees as "rumdums" in a city council meeting.
That set off a series of angry letters published in the open forum column of the local newspaper, The News Tribune:
Fate had other plans however. Just days before the concert, the organizers received a telegram from Canned Heat's management informing them that the group would have to cancel. The telegram, which would be published in the News Tribune, read:
THIS SHALL ACT AS OFFICIAL NOTIFICATION OF CANCELLATION OF THE CANNED HEAT ENGAGEMENT TO BE PLAYED THE WEEKEND OF JULY 31 - AUG 2. ALAN WILSON SINGER-GUITAR PLAYER OF THE GROUP HAS BEEN HOSPITALIZED FOR THE PAST TWO WEEKS FOLLOWING A SERIOUS AUTO ACCIDENT. HE IS STILL UNABLE TO LEAVE THE HOSPITAL AND IS UNABLE TO PERFORM ANY ENGAGEMENT UNTIL FURTHER NOTICE FROM HIS DOCTOR. A LETTER FROM HIS DOCTOR AND CANNED HEAT INC IS FORTHCOMING TO YOU. WE ARE EXTREMELY SORRY THAT WE MUST CANCEL THIS ENGAGEMENT CORDIALLY = SKIP TAYLOR, PRESIDENT CANNED HEAT INC
Alan "Blind Owl" Wilson's auto accident was believed to be a suicide attempt. Sadly, he would die just over a month later (September 3, 1970) from what was ruled an accidental overdose.
Music Festival Still Goes On!
Without Canned Heat however, the concert had little chance of living up to the hype. Advanced ticket sales were already below expectations before Canned Heat had cancelled and their departure from the bill all but guaranteed a low turn out.
Still, rumors circulated that thousands of advanced tickets had been sold and that hordes of hippies were camped out west of Peru.
Come the night of the concert, several neighboring towns sent police officers and squad cars to help patrol the area. The Illinois State Police was also out in force while several units of the LaSalle County civil defense group were put on standby.
In the end, however, just 1,412 people attended the concert, mostly kids between the ages of 15-18. The event went off without incident.
The biggest issue that the police had to deal with was the traffic of curious residents, which was bumper to bumper for miles. It was even reported that around 200 people stood across the road from The Back Door hoping to see something happen. They would be disappointed.
Inside however the crowd of young people enjoyed four hours of music on a hot and muggy Saturday night.
Local group 927 Ya Ha Band performed first. Next was local group The Rain which included members Dick Verucchi, Les Lockridge, Dick Hally and John Mark Edmunds. (The group would record a single for RCA as Stronghold about a year after this concert. Later several members would form the group Buckacre.)
According to the News Tribune, reactions of local residents to the concert ranged from "I knew everything would be okay" and "I'm glad nothing happened" to "It's a good thing the police were so well-prepared."
In the week after the concert, the paper continued to publish letters to the open forum, mostly denouncing the fear and close-mindedness that had surrounded the event.
