Irish,

I think the song you are looking for is "Cats in the Craddle" By Harry Chapin.

"Cat's in the craddle and the silver spoon, little boy blue and the man in the moon, when you comin home dad, I don't know when....but we'll get together then, son. We're gonna have a good time then...."

I don't think Croce actually sang it...but the two are easily confused.
