Sully and Mac

Sully and Mack did all right. The “wop” comic got powerful laughs and remained consistently in character throughout, piling up an impression. The straight man was wonderfully straight, and used “Do you mean to tell me?” and “Let me understand you clearly,” and wore perfectly fitted clothes, and sang a mother ballad, playing it according to Hoyle. Not that it wasn’t what the act required – it certainly was. It as a strong team, the work is fast, and the finish was a wallop.
