as an american, i wish i had grown up with this!! i'm going down a bit of a youtube rabbit hole of grotbags clips and i absolutely love everything i'm seeing! outtakes from puppet-based shows are always such a delight, i love seeing how the puppeteers work in the character movements and voices even while they're joking around!
I'm glad that you enjoyed the outtakes. If you enjoy watching puppeteers at work, take a look at Of Muppets and Men (Muppets documentary). As well as Grotbags, Central Tv also produced Spitting Image. Another puppet show that was recorded in Nottingham was Paz. The outtakes are yet to be uploaded...
Bloody brilliant!!! Nothing like this on telly anymore :( massive shame :( proper entertainment! (obviously I know these bits never went out on kids TV but still, grotbags ruled!!!)
