All the Dirty stuff is kinda confusing. Here's how I understand it. First, we're talking about 3 distinct tracks here: Dirty, Dirty Epic, and Dirty Guitar.

Dirty
-----
First appeared under Lemon Interupt on the Dirty/Minneapolis records and promos. I don't know the lengths of the track for those records, but if it's 11:14, then we can assume that as the original edit length of Dirty.

Next appeared under Underworld on the Dirty Epic/Cowgirl EP as "Dirty Epic (Dirty Mix)" which was 11:14.

Last appeared under Underworld on the Anthology (U.S. version) as "Dirty" at 10:17, which just fades out the last minute of the full 11:14 mix. I know nothing about the timings on any of the other countries' Anthology tracks you have listed.

Dirty Epic
-----------
Complete rework of Dirty. Always appeared under Underworld.

First appeared on dubnobass at 9:55.

Next appeared on the Dirty Epic/Cowgirl EP as "Dirty Epic (Album Version)" at 9:52.

Finally appeared on the Anthology at 9:59. Differences in timings are all just minor variations in the fade out and mixing.

Dirty Guitar
-------------
Remix of Dirty with more emphasis on the guitar, etc. Always appeared under Underworld.

First released on white label promo in 1993 as "Dirty Guitar" at 10:00.

Released on Dirty Epic/Cowgirl EP in 1994 as "Dirty Epic (Dirty Guitar Mix)" at 10:00.
