WeLoveKnott is a “supplemental page” because… well… that’s how much stuff he has put out. Mike needs a whole fleet of MySpace pages. Great idea. Check out the page and enjoy the songs. I guess they also noticed this page, so I should work harder on getting it finished

I found some more information on the Shisho, Connie Dungs, and Inkwell Collective tribute/cover songs. I think the Shisho one is the only one still available, and can be picked at shisho.info.

The Inkwell Collective have a song on their MySpace page that is “written for” Mike Knott. The song is “Hello Hospital.” It’s pretty cool: http://www.myspace.com/theinkwellcollective
