When Perry, Della, and Paul arrive at "Natasha's", a dance club, and before they go inside, an instrumental version of Petula Clark's 1965 hit song, "Downtown" is playing in the background.
When Howard Bayler exits his convertible with the car radio still on, the music playing is a surf rock instrumental version of "Jersey Bounce", a 1942 big band hit for Benny Goodman.
The last of five appearances in the series by Mala Powers.
