Finding an exact match to a script font is difficult. WhatTheFont (suggested in a comment above) shows Flemish Script II by Monotype and Lockhart by Danie Type among the choices. These come close, but are not quite right, especially the capital C.

To help any of these tools, remove the black drop shadow and the top line of text. It also helps to darken the yellow to create more contrast.
