Boom Boom (Mabel song)

"Boom Boom" was the Danish entry in the Eurovision Song Contest 1978, performed in Danish by Mabel. This was Denmark's first entry since the Eurovision Song Contest 1966, an absence of twelve years.

The song was performed sixteenth on the night (following Greece's Tania Tsanaklidou with "Charlie Chaplin" and preceding Luxembourg's Baccara with "Parlez-Vous Français?"). At the close of voting, it had received 13 points, placing 16th in a field of 20.

The song is sung as a dialogue among friends, with one explaining that he is suffering from an illness. The others suggest what it could be, but he reports that a trip to the doctor resulted in a diagnosis of being in love - with the rhythm of the heart being the title of the song.

It was succeeded as Danish representative at the 1979 Contest by Tommy Seebach with "Disco Tango".
