"On the Reeperbahn at Half Past Midnight" (German:"Auf der Reeperbahn nachts um halb eins") is a 1912 German song by Ralph Arthur Roberts, originally written for a musical revue.
The song refers to the Reeperbahn, the red light district of the port city of Hamburg.
The song's popularity received a major boost when it was used in the 1944 film Große Freiheit Nr.
[1] The tune was used for Billy Wilder's Witness for the Prosecution (1957), sung by Marlene Dietrich with new English lyrics as "I May Never Go Home Anymore".
The song has been parodied numerous times including Mike Krüger's On the Autobahn at Half Past Midnight (Auf der Autobahn nachts um halb eins).
