California Highway Patrol spokesman Rick Quintero says a big box van decorated with Imperial Stars' logo stopped on the southbound U.S. 101 near Sunset Boulevard at about 10:30 a.m. Tuesday, blocking four of the five lanes. The driver took the keys and fled in another car, then three musicians climbed on top of the van and began to perform.
Quintero says they were arrested and the truck was finally towed away around noon after causing a mile-long traffic jam.
Quintero says the musicians could face charges of obstructing traffic.
The group, whose credits include "Traffic Jam 101," says on its website it is dedicated to helping homeless children.
