I hear that it has been commissioned and is in pre production as we speak, I spoke with Ade Edmonson at an Idiot Bastard Band gig not that long ago and he said as much then, nice bloke.
I saw all the live shows of Bottom back in the 90's they were brilliant.
Also if you want a good night out with very alternative music go see the Idiot Bastard Band, they are touring at the moment and playing the Wyvern soon and are made up of Ade Edmondson, Phill Jupitus, Neil Innes & Rowland Rivron plus the occassional other guest...funny and a good night out.
