Boney M. – Nightflight To Venus

Four versions are known to exist of this album, contentwise, with varying track durations. The longest versions can be found on earliest pressings. The versions can be identified by the (actual) length of the first track, "Nightflight To Venus", the only track with a different duration on each version. The track is a medley with the following track, "Rasputin". On the first version "Nightflight To Venus" is 7:11 (medley 13:37), on the second 5:55 (11:58), on the third 4:58 (10:48), and on the fourth 4:46 minutes (10:37).
Note: The durations above refer to the actual length, which can vary greatly from what's printed on the sleeve or label.

The fourth version, considered the 'final' or 'finished' version, is the most common and appears on most copies. All official CD's contain the fourth version. The odd LP on a non-Hansa label may contain a version other than #4. Some cassettes are also known to contain a version other than #4. No label seems to have released all four versions.

List of observed 'German' matrices (in the style "26026 A-12 /78S II Made in ") corresponding with the 4 versions:
First version: A-1, A-2 / B-1, B-2
Second version: A-3 to A-8 / B-4 to B-8
Third version: [none]
Fourth version: A-9 to A-13, A-21 / B-9 to B-11, B-13, B-14, B-16

The third version can be found on issues at least from Canada, Italy, Japan, Portugal, South Africa, the UK (also fourth), the US and Yugoslavia.

Versions with non-matching combinations on the same vinyl have not been observed, for example 'Second version' on A-side, 'First version' on B-side. Many sleeves come with the set of durations: 5:15 / 5:10 / 3:45... – but actual tracks of these exact lengths are not known to exist.

Note: There are more than one sub in the master per each version, on the same label and with the same cat#, explained by physical differences on the releases. For example, all of these Hansa LP pressings from 1978 contain Version 4: Nightflight To Venus.
