I went to see The Muppet Show On Tour (Second Run) when I was about 7. It was a surprise for my birthday. From what I remember it was amazing. The Muppet Babies bit was pretty short and not all the characters were present but they performed the Muppet Babies title theme. I remember that it had been re-recorded because the likes of Kermit and others weren't there so other characters had to perform their parts. They were puppets while the rest of the show was performed by people in full-size Muppet suits. The only thing I have left from then is the tour program which is a little worse for wear.
