the words, or even title had something like " we are all made of glue"
I think it was an american singer, perhaps a children's song, and the reason
it has come to mind is there is a book out with the same name, and i remember this song from quite a long time ago.
if, by a song from a long time ago, you mean many years, what about the song that had (about 50 years ago) " all made from ticky tacky " somewhere in the lyrics, by some one like peter,paul and mary? bit vague, but half a century is a long time.
