Bon Bon And Trixie's Puppet Show

What were the background ponies of Ponyville doing in the towns Trixie futilely tried to do her magic act in after the Ursa Minor incident? Bon Bon knows, and she doesn't like it.

Trixie magically showed off her bad luck at trying to do a show following her humiliation in Ponyville, and it wasn't pretty. But why do some of those ponies we see in those scenes look familiar? Bon Bon remembers. But had to happen, had to happen, right?
