HOLLYWOOD (CBSLA) — A fire in a building apparently housing a marijuana grow operation prompted an evacuation at the Fonda Theatre in Hollywood next door, where the band Cowboy Junkies was finishing up its tour.

The fire was reported at about 8:40 p.m. inside a one-story building at 6140 W. Hollywood Blvd., Los Angeles fire spokesman Brian Humphrey said.
