"Frisco Blues" and "Old Black Crow" are on vol 1 of the Allen Bros; "Hey Buddy" is on vol 3.

I don't have the CDs but do have downloads of most of the tracks on vol 1 and vol 3 from eMusic. "New Chattanooga" seems to be missing from vol 1, while vol 3 omits three issued titles (while salvaging some unissued recordings from tests): "Tipple Blues," "Mary's Breakdown," and "Can I Get You Now." In the case of "Tipple" and "Mary's," it's not out of the question that no copies of the 78 have been located. "Now" is the flip of "New Deal Blues," which is included on the set, so its omission is a puzzle.
