As much as I like how Rick Wright sneaks in a bit of the Dr Who theme (like on One of these Days) when playing Sheep live (listen to the concert where Roger "spits on the fan"), I gotta say that Pigs (Three Different Ones) is my favorite song on the track. I kinda like Dogs, but I never was able to really get into it. Pigs is such a great rocker that I forget about Dogs. And then the sheep get mad because the pigs get all the attention........
