For those unfamiliar with this show:
Before we get too far into the realm of guests "participating" in FotLK...
Were there any kids sitting in the front two rows?
If so, were they willing to get up and march (many are too shy.)
Unless we're talking about the quick bits about making animal sounds that is really just the "pre-show,"
the CMs only pick little kids to "participate" in the actual "show" and then, its just a little bit of marching around (sometimes carrying a shaker or other noise-maker)
during one of the last songs in the show.
Not a lot of major "participation."
