I'm curious about the position handed out to certain Muppeteers called "Muppet Captains". For example, a number of projects from the 90s credit Kevin Clash as the "Muppet Captain", likewise, in more recent years, that title belongs to Bill Barretta. What exactly is a Muppet Captain? Is it something along the lines of like a chief/head/lead puppeteer? And if so, with all respected intended to both Kevin and Bill, why wouldn't such a position be given to someone with more seniority, like say Frank Oz (back when he still worked with the Muppets), or perhaps Dave Goelz considering he's been involved in many aspects both in front and behind the camera since his beginnings? Again, just curious.
