As with Milton's Café, I wasn't quite as connected to the Dullards as I was to Crux, so the information here might be be a little vague, sketchy, or flat out wrong (at least for now). I think the lineup was as follows: John Baez on guitar and vocals, Trevor Montgomery on guitar, Todd Baio on bass and vocals, and Egg (Jon Hughes) on the drums. (Egg was later replaced by Jeff Shannon, who was later replaced by Tom Ackerman.)
While still sharing the Minutemen/Firehose influences of Milton's Cafe, The Dullards went a step heavier with elements like Fugazi and Soundgarden creeping in. They, too, put out a self-titled cassette on Thick Records. Trevor Montgomery later replaced Sim Flick in Crux before moving to San Francisco where he played with an outfit called Lloydgrove. He was found more recently, however, in Tarentel (with Egg), The Drift, and now Lazarus. At this time I'm not sure what Todd's up to, but hopefully some links will surface soon . . .
Prior to the Northern California migration of most of the Dullards membership, it seems that Egg, Jeff, and Johnny wound up playing together in a group called No, Like This . . . (this link takes you to an interesting page I found with more detail about Egg, Jeff, Johnny, Bad Hair Day, The Beauty Recognizers, etc. -- plus you get an additional perspective on the Redlands "scene" at that time). It seems that Johnny and Jeff continued to colaborate in San Francisco, but I don't know the details . . .
