John Martyn – One World

The two mixes:
On first release the album had two quite different mixdowns. They are often referred to as the 'UK' and the 'US' mixes although the reality is slightly more complex:
Mix #1) known as the 'US Mix' appeared on the original US, Canadian and Italian vinyl pressings.
Mix #2) known as the 'UK Mix' appeared on all other UK and European vinyl pressings.

The differences are often subtle but all tracks differ in some way. There is an entirely different drum track on 'Big Muff'. 'One World' features no scat vocals from Martyn on the intro on the US Mix. Elswhere the mixes feature different instrumentation levels, such as a very different emphasis on the percussion on 'Certain Surprise', L-R positioning such as the drums on the US Mix version of 'Dancing' being mostly in the right channel, central on the UK Mix, equalization where every track has differences with the same applying also to levels of reverb and echo.
Overall track times also differ. Most notably the US Mix version of 'Dancing' runs 3:55 while the UK Mix version runs 3:46 and 'Big Muff' runs 6:15 and 6:28 respectively.
The US Mix was not issued on CD until the 'Deluxe Version' 2 CD set in 2004
There is no release which states anywhere on the packaging which mix is used.
US Mix versions of 'Dancing', 'Sweet Certain Surprise' and 'Dealer' appeared on 'The Electric John Martyn' compilation in 1982 and the US Mix version of 'Big Muff' also appeared on the B side of the 12" Single 'Johnny Too Bad' in the UK in 1977.

The running order:
It remains unclear how this was intended to be released. On the rear of the LP sleeve the first track A1 is "Couldn't Love You More". But for some reason many issues have a reversed tracklist. Side A actually being Side B. Other issues have changed / reversed label colour sides. Usual "Day & Night" labels became "Night & Day".

"The sleeve of One World was completed before the album was delivered, hence the odd running order on the back of the sleeve, with the sides in reverse order. For years, many loved the album beginning with Couldn’t Love You More and ending with Big Muff." http://www.johnmartyn.com/sleeve-notes/one-world-deluxe-edition/

Nevertheless all CD issues have "Dealer" as first track.
