What begins as a camp blues number is shortly transformed into a spacious mature jazz vocal. ???When Will You Call??? recalls the ???Days of Wine and Roses??? style pop-jazz of the 1960s done by artists such as Johnny Hartman, Nancy Wilson, and Barbara Streisand, but with a harder edge as he sings on the song???s bridge ???No notice, no letter, you just packed your shit and left.??? By the song???
