Hey Tony,
There are a couple reasons why you can't sing like Donny. First and foremost, Donny is from New Jersey--the same place Frank Sinatra hailed from. Consequently, he has that great, New Jersey accent that Frankie had, therefore, it's gonna' be real tough to match that. I've heard him in person, and I can tell you that he sounds even better when performing live. He's going to be tough to match when it comes to being a performer and singer. All you need to do is jump on a plane, fly over the pond, spend about 40 years in central New Jersey and with luck, you'll pick up the accent and be able to "sing like Donny Pesce."

Cheers,

Gary
