The Danish participating broadcaster, Danmarks Radio (DR), organised the Dansk Melodi Grand Prix 1966 in order to select its entry for the contest.

The reasons for the withdrawal are unclear, although it is believed that a new programme controller at DR did not consider the expense involved in Eurovision participation to represent value for money.

Danmarks Radio (DR) held the Dansk Melodi Grand Prix 1966 on 6 February at the Tivoli Concert Hall in Copenhagen, hosted by Annette Faaborg.

"Stop – mens legen er go'" had a contemporary sound and featured an instrumental break during which two dancers performed an energetic routine.

Each national jury awarded 5-3-1 to their top three songs, and at the close "Stop – mens legen er go'" had received 4 points (3 from Finland and 1 from Norway), placing Denmark 14th of the 18 entries.
