Commercial for Hostess Snack Cakes, likely from the '70s. 

Shots of kids engaged in different activities like potato sack racing, swimming, walking down the street in a group, camping, and playing with their dog. 

Song: “Kids’ stuff, swimming, tug of war! Dancing school! Hostess! A kid’s world is a special world, and Hostess is a part of it; Hostess and kids: they go together!”

Voiceover as kids eat the listed items: “Fresh, wholesome Hostess. Cupcakes, fruit pies, golden Twinkies with cream filling!” 

Song: “A kid’s world is a special world, and Hostess is a part of it; Hostess and kids: they go together!”
