I just Googled the Blue Dog and found this thread. I of course remember going there with Bobby C.,singing at open mic, and meeting many performers including Dave Van Ronk. Maybe it was the Foghorn by then. I still have my sketch pad that I decoupaged with the playbills from there. How about the Peabody Bookshop? I moved back to this area a few years ago and would love to find good folk. My bro still plays bluegrass.
