i was watching city confidential on A&E channel...they talked about philly and this dentist named Dr. levin who hustled his way through Univ of Penn dental school...first dealing small time drugs then investing his money in the record company who released "double ductch bus" song (made a bundle but didntpay the artist, he started a FBI investigation on Dr. Levin) in graduating to cocaine and living a double life in the subs of devon....pretty infamous. op:

There's a great book about Larry Levine written by Mark Bowden (a Philly Inquirer reporter who also wrote Black Hawk Down and killing Pablo). You should pick it up, it's a great read.
