Post Alpha Bits Cereal Commercials

[Hawkee]

On my commercials DVD I found two commercials for Post Alpha Bits Cereal and I would like to know if you remember them? The Alpha Bits Cereal commercials appear to be from the 60's and I am curious to learn more info about them.
1. Post Alpha Bits Cereal Commercial #1
This commercial starts with four kids exploring a house with a Frankenstein like character and then after they explore the house the kids eat bowls of Alpha Bits Cereal with the Frankenstein like character and throughout the commercial a singer sings a song about Alpha Bits and it makes think that James Brown sings the song because the singer sounds like James Brown
2. Alpha Bits Commercial # 2
The second Alpha Bits commercial is in black and white and features kids playing outside with animals and uses the same melody of the song of the previous commercial but with a folk/country music sound and the singer sounds like Roger Miller and it makes me think that Roger Miller sang this jingle

There was also a Post Alpha Bits Cereal commercial with Michael Jackson and The Jackson Five and came out in the 1970's

I found that there were also colored versions of the first two Post Alpha Bits commercials I mentioned and they seem to be rare versions
