What we have here is the demo version of 'Slow Show' from the National's wicked-awesome album Boxer. Noteworthy differences from the final version include an alternate chorus ("everything you say has water under it"), a different bridge, and no '29 years' part at the end.
This demo version was included on a free disc called the Liberation CD that the band distributed in France to coincide with the release of their new album. Also included on the disc was a demo for an unreleased song named 'Tall Saint' which is definitely one of the National's best tracks. As the Christmas season is now upon us and I've been overwhelmed by the spirit of giving, I've included it below.
