How do you make Extended Version of a track with out Re-recording it

[DreaminginStereo]

you buy a single and it has these mixes on it

Album verion
Instrumental version
Extended Mix


how do they make an extend version of a song that is longer then the album version?

And what is the Diffrence bettwen a Extended Mix and Extended Version?


Thanks

They have access to the masters.

These extended play ones are commissioned by the Record company because of regulations concerning Single release to qualify for the UK Singles Chart.
