In my collection I have three different versions:

- Swedish Polar Pressing (POLS 252)
- German Polydor Pressing (2374 111)
- Eastgerman Amiga Pressing (8 55 465)

The swedish version includes the Track "Waterloo" in swedish and english (12 track LP). The front cover of the LP includes a red sticker ("Grand Prix of the 1974 Eurovision Song Contest"). All pressings outside Sweden were released without the swedish "Waterloo" version (11 track LP).
The eastgerman version has a different coverartwork and includes the track "So Long" instead of "Honey Honey".
There is also a pressing from USA available. This version includes the US remix of the track "Ring Ring" as a bonus track.
