I frequented the Blue Dog Cellar after it moved to the outer portion of Baltimore, I believe on York Road. The old location of the Blue Dog Cellar, near downtown Balto., was quite rustic, with real brick walls inside. It was remodelled and became the Foghorn Folk Center. Upstairs were all kinds of folk music books, etc., while downstairs was the coffee house. At the grand opening of the Foghorn I met Josh White; he was sitting at a table and drinking Cutty Sark with the other folk performers, including George Stevens, form the Blue Dog. You also might remember the Blue Dog East on the boardwalk in Ocean City, MD. Spent many a night there as a mischevious high school student w/my other folkie friends. Some names you may remember from the Blue Dog coffeehouses, and the Foghorn, include Biff Rose, Hoss, of course George Stevens, the owner, and the great Bob Sessions. Heard and met them all. You also might want to find the old LP album Urban Folk Renewal which has live performances from the old Blue Dog. (The Balt suburbs, in Lutherville, had Patches Fifteen Below, a coffeehouse started by TV personality, Patches. Located 15 steps down in a basement, it borrowed many of the Blue Dog performers. I did all the coffeehouses back then; played guitar, and was a real folkie.
