All Music Guide - James Wilkinson
Following the Mardi Gras-influenced funk excursion that was Smokey Mary, Every Man Should Know finds Harry Connick, Jr. in cathartic mood. This, his 30th album, is the seventh on which he has written and arranged every single track. Guest musicians featured include both Wynton and Branford Marsalis as well as the Nashville-based guitarist Bryan Sutton.
