It was blue, and there were modern pop culture references, but he was far more similar to comedians from the 50s and 60s than he was to say, Richard Pryor, the comic he's most closely associated with. Look at the material his best contemporaries...Steven Wright, George Carlin and even Rich (Live at the sunset Strip preceded Delirious by a single year) were doing, and tell me Eddie's material isn't a throwback to an earlier era.
