Spalding: No one is trying to figure out how to package me. I've enjoyed my eccentric castings. I stretch between two Dalis – the Dali Lama and Dolly Parton.
Spalding: People want to have me to dinner. I'm not Mr. Quick. I'm not a great social satirist. I need time to absorb life. I spend a lot of time mulling, cogitating.
