In 1980 Vancouver band Doug and The Slugs released their debut album Cognac and Bologna. The album's first single was the Top 20 hit "Too Bad". (The Intro of that song was the Riff-In-A-Jiff entry for May 21, 2012.) The follow-up single was "Chinatown Calculation", the Intro of which is tabbed here.
