The last performance at the improv festival was led by Laura and Rick Hall, professional comedians who appear on the popular TV show Whose Line Is It Anyway? They enlisted a number of performers from other groups and non-professionals who had taken their workshop earlier in the day.
One of their techniques was to take an idea from the audience, turn it into a song title and require the performers to make up a couple of lines on the spot, then pass it down the line. To no one's surprise, the content of the songs veered off in strange directions. A lot of pressure on those onstage but the audience loved it.
