Mon Amour was shelved soon after the single's release, although much of its material was worked into Klaus Dinger's debut solo album Neondian, including a remixed version of "Ich Liebe Dich".

In late 1982 Hans Lampe announced he was leaving the band, embarking on legal action to reclaim his share of La Düsseldorf's advance, which Klaus had used to build the studio.

In advance of Valentine's Day 1983 Ich Liebe Dich (German for "I love you") was released by Teldec, backed by a bizarre promotional campaign in which the Dinger brothers filmed themselves spray painting a huge graffiti heart onto the road surface of Königsallee; a Düsseldorf street.

Whilst not technically instrumental (the Dinger brothers whisper "Ich Liebe Dich" and "Jag Älskar Dig" over the music) the A-side harks back to 1979's Rheinita in its sound, being primarily synthesizer-driven.

The legal battle over the money and the rights to La Düsseldorf's name and music continued well into the 1990s, Thomas and Klaus finally reaching a settlement in 1997.
