Anyone who's even a little bit involved in the art of mentalism should know the names of the following people: Bill Cassidy and Max Maven.
Then where does that leave you? I think you mean BOB Cassidy.
P.S. The whole "who's better" mentality is really quite silly. Both have distinct and effective manners of presentation, yet both provide professional and satisfying entertainment for their respective audiences. The thing truly worth pondering, in my opinion, is how you can learn from them both. NT
