I only remember that it is a live action movie that starts out with a mickey mouse cartoon to the tune of “strolling through the park one day”, and then goes live action from there. If I recall, it’s about housewife spies.
I think the movie starts out a some kind of outdoor drink stand and has beer barrel polka playing.
Here is an old Disney short that has Mickey & Minnie
in an old-timey scenario.
The Nifty Nineties (1941)
This also includes the song “While Strolling Through The Park One Day”.
Officially known as “The Fountain In The Park”
No live-action, but is 7 minutes long.
Could it have been shown before the main feature?
If you are an old ‘Wonderful World of Disney’ fan, they used to do that on NBC.
It’s the feature that I’m looking for, but that’s the right cartoon.
The cartoon has Mickey and Minnie on a tandem bicycle.
