But not in such an obvious place. . Now see the shark how red his fins are. As he slashes at his prey. Mack the Knife wears fancy gloves. Which gives a minimum away. . By the Thames' turbid waters. Men abruptly tumble down. Well is it plague or is it cholera. Or because Macky's in town?. . And the child bride in her nighty. Whose assailant's still at large. Violated in her slumbers. Macky how much did you charge?. . In the ghastly fire in Soho. Seven children had a go. In the crowd stands Mack the Knife. But he isn't asked and he don't know. . In the crowd stands Mack The Knife. But he ain't asked and he don't know.
