First off, this isn't even a full length performance, but rather a short 45 minute gig, recorded in a pub back in 1991. Everything about the show is poor and the performance is not up to much either.
The audience makes absolutely no effort to engage in the show and this all results in a rather dull affair from every angle.
In short, even if you are an Alan Davies fan, avoid this. It is not a rare collectors item. This is just a poor product that is not much better than a bootlegged recording. 2 words, rip off.
