Dragnet

"Dragnet" is an instrumental theme from the radio and television show of the same name. It was composed by Walter Schumann for the radio show, and was also used on the subsequent television series and later syndication of the TV series under the name "Badge 714". The theme is in two parts: an opening signature "Main Title" (the ominous "Dum - - - de - DUM - DUM") and the "Dragnet March" used over the end credits.
