If it doesn’t say on his web site, I would have no knowledge of his particular technique. I have done several myself. Yes, you want a panorama head (day or night) though for night a stable one is important.

A fast lens is nice but of course if you need depth of field you can’t really use it and must take a long exposure.

A number of panorama packages will let you handle moving people, if you can adjust the blend zone (or like photovista, they naturally use a small one.)
