The noise in the Pacific National Exhibition’s Agrodome was ear-shattering Monday night — but for city police it was quiet.

At least, that’s how Inspector F. C. (Bud) Errington described a rock ’n roll performance headlined by the British group, Herman’s Hermits.

“It was one of the quietest shows we’ve had to control,” said Errington, head of the police department’s special detail.

“We didn’t have any appreciable casualty list and we usually carry out about 30 persons,” he said.

Only four girls were treated by St. John Ambulance volunteers during the two-hour show, which also featured The Who and The Blue Magoos.

A St. John spokesman said three of the girls suffered from shock and the other suffered a broken tooth when she was hit by a piece of a guitar thrown into the crowd of 4,200 by a member of The Who group.

The group, which preceded the Hermits, ended their performance by setting off smoke bombs and breaking their guitars and drums.

Errington attributed the lack of casualties at the show to a specially-constructed stage which put the performers 12 feet above the Agrodome’s floor.

Errington said because the stage was solid there was nothing the crowd could try to get through such as in previous rock ’n roll performances, when police tried to keep the crowds behind a three-foot fence surrounding the stage.

And, he said: “With the high stage, if the kids crush right up against it they can’t see anything anyway.”

Errington said 22 policemen and two policewomen were on duty at the show.

About 10 youths were ejected by police from the floor of the Agrodome during the show.
