It is getting more and more problematic, to detect all known versions, also for MK or his people, who are involved in record-producing or record-manufacturing.
Other example the song Money for Nothing: but there are some known different versions in duration only. Maybe MK has also totally different arranged versions on his reels in his vault.
MFN Extended Version - 8:24min Included on the CD-Album Version of BIA and on the Vinyl-12-Inch Maxi-Single Version
MFN LP-Version - 7:04min Included on the LP-Version of BIA and on the US-Promo 3-Track Vinyl version
MFN (Long Edit )Single-Version - 4:38min Included on the original 7-Inch single version and on the US-Promo-3-Track vinyl version
MFN (Edit) Single-Version - 4:05min, Included on the original 1988 LP and CD-Albums, on the US-Promo 3-Track vinyl version, on the 2-Track CD-Single from 1988 and on the 7-Inch 1988 single from Holland.
So that is a little example by my side, how many durations are available of songs. Maybe there is something to discover new, if MK or the other record-producing-people discover other variants in duration or in composition. I hope so.
