"At its best, Have Fun With God works well as an experiment and as a listening puzzle to work through. If you know Dream River well-and it's hard to imagine anyone else being interested in this record-you'll hear new things in it after giving this record a couple of spins. It also seems safe to say that, despite its charms and left-field nature, Have Fun With God will be a minor entry in the Callahan catalogue, remembered about as well as his low-key 2010 live album Rough Travel for a Rare Thing, which is not to say I'm not glad both exist".
