There's also Mark Tarver's Shen (http://www.shenlanguage.org/). I don't know whether it's a Lisp 1 or 2, but I wouldn't be surprised if it's also a Lisp 1. I have read about Shen but not programmed in it, but I see it's added quite a few features absent from Common Lisp and the newer Lisps, which I think are worth having.
I decided to read up on Shen, and followed some reddit threads about it, and the consensus seems to be that it is a very inefficient language and many of its abstractions are not actually portable between platforms, i.e. the language changes a bit depending on where you use it.
