You mean the Black Session 1992? It's true that there're so many differences in the lyrics. Considering the time when this came out, maybe it was like a demo?
Yeah the Black Session one is interesting but the best version of all is from the Peel session. Not mired in reverb like on His'n'Hers, much more natural energy in the vocals and the instruments are a lot clearer. One of my favourite Pulp session performances - sleazy, superb, epic-sounding.
