Michael says exactly what I have said in the preceding post. I have it in my files. Thought Sonny was his dad, thought Sonny adopted him, realized Sonny is his actual biological father. That sums it up

Although I can't remember exactly what he said a month ago right now - I offer you this to start with from his book "From Godfather to GOD the Father". Page 21 of the Family Section this paragraph in part:

"And, as young as she was, Mom had also been married before. At sixteen, she hooked up with a handsome young soldier named Louis Grillo, and their teenage love affair, although it barely survived a year, had produced none other than yours truely-me. I was Louis Grillo's son by birth, but as far back as I can remember, Sonny Franzese accepted me as his own. He was, therefore, the only dad I ever really knew."

I will try to come up with more later and see what your research came up with and when. It doesn't mean that he didn't say it differently at different times. Lots of stories change over time.

Also that same partial paragraph with only a word or two changed is stated in his 1991 writing of the Blood Covenant on Page 34 of the Old Life section 7.
