Impressive 3-panel flyer by Dave. There were photocopied as A5 booklets with the larger panel inside (I've arranged it this way to try and make best use of the page layout here).
This gig was possibly cancelled or postponed (and I've been trying to avoid posting anything that didn't take place); however CAT ON FORM definitely played there later in 2003, and it's such a great flyer.
These ones definitely DID happen at the Mumbo that month (put on by various other people):
07/06 - Lost Film Fest
13/06 - 90 Day Men, Shining Reserves, The Wow
30/06 - Pedro the Lion, The Jesus Years, Burnst
