Well, Thats Diddy Daddys signature, so maybe any authentic signature / handwriting may be a close alternate.? :)

( Slightly ) Calligraphic Handwriting Scripts.: 'Carpenter'; 'Dearest'; 'Lanier'; 'Sudestada'.. ( But, I may still recommend that you use actual handlettering.. )

Dav, formlos

That's the problem, my handwriting is so
crappy..it wouldn't make a great signature.

John,

Instead of buying a font, you could hire a lettering artist. Check out Mark Simonson's work.
