The performance of Astoria have been a hot topic before. Even the puppeteers that worked on the episode are not sure who did it, as you can see from the talk page Talk:Astoria.
So if you are sure it's Steve you need some other evidence other than "I recognize the voice"
Thanks for chiming in, Henrik. Yeah, the Astoria talk page has a long string of guesses ranging from Steve to Jerry Nelson to Bob Payne. Basically, it sounds different to other people, so we would need more definitive proof than a guess. For more info on this point, I would recommend reading Muppet Wiki:Name That Voice.
Currently, Murray's PIYN segments are in the live-action sketch category, but that category is for sketches that don't have Muppets appearing on a regular basis. Would it be okay for me to change it to the recurring sketch category?
Yikes, that's two really dumb typos I've made in the past week that you fixed -- thanks! Lately, I've literally got 3 or 4 different things going on at the same when I'm editing the wiki. Got to pay closer attention :/
Eh, it happens. When I've done coding, I'm usually annoyed whenever I misspell a word or forget to add something; often it's a tiny thing I wouldn't think to double-check. Still, when I'm on the wiki, I generally like looking out for errors I can fix, so it's not a big deal ;)
