Ran across this on You tube... toward the end of this 1978 commercial compilation reel, a spot featuring Dick Van Dyke for the Kodak Handle Camera (an instant camera later pulled off the market for its surprising resemblance to the Polaroid).
The music is by Mike Love & Celebration, with Dean Torrence featured prominently on falsetto. The radio version played incessantly on Chicago's Big 89, WLS, in the summer of '78, occasionally right after Almost Summer.
Spot starts at about the 8:11 mark.
