Byte September 1981 did have a nontrivial program in Lisp: it parsed, differentiated, and simplified algebraic expressions. (I remember it fondly as my first Byte issue and first exposure to Lisp and calculus, the latter two almost equally mysterious. But going back and rereading the code, it was amateurish.)

I don't remember any Lisp in Basic in either Byte or DDJ, and I'd have probably seen it.
