Description: 21 Jump Street is about a group of under-age looking cops who go undercover at high schools to catch young criminals before they become older, more dangerous criminals. In later seasons, the team went less and less undercover on high schools, and the plots focused more on the cops' personal lives. THEME SONG: The theme song was written by Liam Sternberg and sung by Holly Robinson - with backup vocals by Johnny Depp and Peter Deluise. The lyrics were: We never thought we'd find a place where we belong. Don't have to stand alone, we'll never let you fall. Don't need permission to decide what you believe. I said jump, down on Jump Street. I said jump, down on Jump Street. Your friends will be there when your back is to the wall. You'll find you'll need us cause there's no one else to call. When it was hopeless a decision is what you need. You'd better be ready to, be ready to jump. 21 Jump Street. FILMING LOCATION: The series was filmed on location throughout Vancouver, BC, Canada.
