The sixth Captain Powerchord strip was drawn for the local entertainments guide 5D, but was not published - I think the magazine had closed down by the time it was submitted. It was written and drawn in August 1994. Note the cameo return of Lampshade Man!
See here for an introduction to Captain Powerchord. In the next few days I will post the seventh strip, a two-pager called The Really Rather Strange Thing That Came From Another World!
