In Swedish, three lyric versions exist, "Mina kärleksbrev dom vill jag ha igen" ("My love letters, I want them again") written by Åke Gerhard and released in 1961 as recorded by Lill-Babs, "Min lägenhet den vill jag ha igen" ("My flat, I want it again") written by Einar Svensson and released as recorded by Thorleifs on the 1974 album "En dag i juni" and "Två ska man va'" ("Two shall you be"), written by Christer Lundh and released as recorded by Lotta Engberg on the 1988 album 100%.
It was the first number-one single on Tio i Topp, which is considered the first official record chart in Sweden[1]
The song was used by the Red Cross for a door-knocking donation awareness campaign on TV in Australia in the 1980s. It had been a #1 hit there in 1961.[2]
An excerpt of "I'm Gonna Knock on Your Door" was used in the Buchanan and Goodman 1961 break-in novelty recording entitled "Berlin Top Ten" which dealt with the Berlin Wall crisis, during the Cold War. Boris the Russian Spinner, introduces the song as "I'm Gonna Knock on your Door" by the Secret Police, but it is interrupted by a breaking news development involving another Cold War issue.
