Mack the Knife, aka The Ballad of Mack the Knife, originally Die Moritat von Mackie Messer, is a song composed by Kurt Weil with lyrics by Bertold Brecht for The Three Penny Opera (Die Dreigroschenoper). the song has enjoyed popularity for almost 80 years, being covered by many, many performers.
Ruben Blades, the Panamenian singer and composer (sorry, Drude for making you homesick for Panama), recreated "Mack the Knife" as "Pedro Navaja" in 1970s Bronx. it is a great song.

*sorry for the lack of cover art. I've had this for ages and can't locate the album it originally came from
