The Raiders toured Western Europe as the opening act for the Beach Boys. Mark Lindsay called it "an eye-opening experience." thanks in part to Dennis Wilson's drug use. "Bruce Johnston was a health nut. He took thousands of vitamins and other pills. Dennis also took thousands of things...not as many vitamin pills as Bruce Johnston," he says.

The people on the tour were concerned that Dennis would get caught with drugs at a border stop. The Raiders and Beach Boys had their own plane for travelling. One time they pulled into Heathrow and were diverted to a corner of the runway. The plane were searched.

The UK police found Johnston's pills and Johnston had to accompany them to the police station. It took several hours for the police to test the pills. Eventually the police had to sheepishly tell Johnston that the tests came back clean. There was no problem with his pills.
