Struthers won her week in 1975, but lost in the Grandmasters week, ultimately to Richard Dawson. Struthers and Kaye Stevens failed to advance to the championship match that exists today with Bill Bixby, Betty White, Hal Linden and Dawson.
The first set of All-Stars winners were Nancy Walker, Peter Bonerz, Don Galloway, Dick Gautier, Joyce Bulifant and James Shigeta. Shigeta won the Grandmaster championship.
Fun fact: Shigeta used his prize money to fund the James Shigeta Scholarship in Asian Studies at the University of Hawaii at Manoa. That scholarship continues to be awarded today.
EDITED to add Joyce Bulifant, based on comment below.
