Gerber Graduate Song?

Okayy, my mom gave me a tape a few years back and it was like a preschool sing a long tape. And there was this song and all I remember it saying was "I'm a Gerber Graduate Now." and I have a 3 year old brother that I wanted to teach the song to but I cant find it anywhere does anyone know what I am talking about and please post a link if you do. I am not talkin about the gerber commercials but a song saying "I'm a Gerber Graduate Now." Thanks sooo much!
