It's pretty apparent Doris Day and the production company are far removed from the psychedelic experience: their idea of a trippy reference effect (and my favorite) is a close up on a stained glass light fixture. The house band actually is a real band, though - The Grassroots - probably best known for the hit "Midnight Confessions" of the same year. Granted, not as keen as The Strawberry Alarm Clock's appearance in "Beyond the Valley of the Dolls", of course, but given this level of vanilla be appreciative as the band could just as easily turned out to be The Lettermen in fringed suede vests and ponchos.
What is interesting though is that as this is being filmed, Doris Day's son, the musician and record producer Terry Melcher, is hanging out with Charles Manson and his hippie family, who, though pre-murderous, are most definitely not drinking coffee in a discotheque and tripping on a stained glass light fixture. Otherwise some great swinging beads, minis, and Sassoon bubble cuts. Enjoy!
