Looking for old snack food commercial

I’m trying to find an old commercial which played on TV in the US in the late 1960s or early 1970s. Problem is, I don’t remember what product it was for. I think it was a snack food, or possibly a breakfast cereal. All I remember about the commercial is it had a song, I think based on a John Philip Sousa march, with somewhat goofy lyrics describing the product. Apparently the product consisted of bite-sized pieces shaped to resemble different objects (like animal crackers, but not animals), because what I remember of the song is one verse described all these objects, ending in the phrase “… and all sorts of crazy shapes.” I think one of the objects was “aeroplanes” (pronounced as three syllables). I vaguely associate this commercial with Screaming Yellow Zonkers, but obviously that’s not right because SYZ are just popcorn, but the product may have been introduced around the same time as SYZ. Any ideas?

Alpha-Bits; you can see it maybe one minute in here.

Awesome! I never would have remembered that it was Alpha-Bits. Thanks.

Susan Dey is in the hair-dryer commercial at 8:07. She looks even younger than she did as Laurie Partridge. :o

I recall another breakfast cereal commercial that used the “Stars and Stripes Forever” music. Rushers had a circus band playing the music while a bunch of circus wagons paraded across the screen, touting Ruskets and Ruskets Flakes. Then the wagons stopped long enough for a lion* to growl at us “There’s a prize in every package!” before rolling on.

*Someone in this thread remembers it being a tiger, but I’m pretty sure it was a lion.
