They are: Bernie Schwartz - lead vocals, Barbara Wallace - lead vocals, Gene Garfin - lead guitar, Gary Davis - bass guitar, Greg LeRoy - drums & percussion, and Tad Barczak - synthesizer & piano keyboards.

Last theatrical movie appearance of Jane Wyman.

During a golf scene Hope is first holding a golf club immediately after getting out of his cart, then is empty handed and removes a club from his bag before getting advice from Mildred to use a different iron.

During the golf match sequence the bag of potato chips Mildred the Chimp is enjoying changes between shots from a full bag to one torn in half then full again.

At the end of the golf sequence an out of place mechanical drinking fountain appears next to the green to serve as a ricochet barrier during Mildred's match-winning putt, never to be seen again.
