Self Made Man - Track Length

I've noticed a few versions of this track floating around. I first heard this on You Tube, and that version is 4.23; I then heard an mp3 with a length of 4.39; and today I was at a record fair and I bought a bootleg with a 4.46 version.

In each case the opening section just gets a little longer. My question is: just how long is this track? Is the 4.46 the 'definative' version or does any one have a longer version?

Thanks

I'm guessing that the 4:23 version is from a convention recording, whilst the other versions are the studio demo version, which differ slightly from the convention recording.

My version of this is 4:39 too, so you might want to check if there is a few seconds of silence at the beginning or end of your bootleg version, as that could lead to the extra length.[/QUOTE]

4:46 seems the correct length, as the track is playing in the right key/pitch here.
