Aside from having fun at the roadkill show, you may have noticed the host point very specifically to a person to ask for a suggestion. That person was none other than Tanis O'Connor, one of the hunt constructors (aka Theotherone). Her suggestion for the madrigals was Advanced Placement. The other suggestion the host got for the madrigal was from Sola Grantham, another hunt constructor (aka Tracy Mount). She gave the suggestion Mystery Hunt. The answer to this puzzle was ADVANCED PLACEMENT. All the other seemingly hunt-related improv was just that: improv. Hope you enjoyed the show!
For historical interest, here is the set list from the Roadkill Buffet show where this transpired.
