I'm certain it's Zapf Chancery Medium Italic. However, it has been altered.
Alteration #1: it has been squeezed. Ugh. Font Sacrilege.
Alteration #2: it has been made artificially more bold using some sort of outline tool (Corel's contour effect, Illustrator's outline or path offset filters, etc.). In making the type more bold it swallowed up many of the more subtle details in the lettering. It's usually just better to find a native version of the script that is more bold. Unfortunately the real bold weight of Zapf Chancery looks much different (the capital letters don't have any of the swash effects).
