Khandu,A bit more on this because it's fascinating.
When CB visits Lucy's "lemonade gone psychology" stand he allowed us to analyze him via his alerego. I E. he could explored very persoanl aspects of himself under the guise of CB. Bob did precisely the same thing spilling his guts on subjects no Como or Crosby would have ventured into. Of course Bob had chemical assistance, but then Schulz had religion - hey whatever works.
Fascinating stuff!
