From the episode "Who Give a Hootenanny". Folk music is what's going on. Fonzie, at first, doesn't understand it, because he's in to early rock-n-roll, and he demanded an explanation from Arnold about why his favorite tune, At the Hop, wasn't in the jukebox. Arnold tells him that folk music is in, but Fonzie is temporarily in disbelief. Joanie and Chachi, when they returned to Milwaukee to appear on a local music variety program, "Hootenanny", thinking they were going to perform rock-n-roll. Of course, Joanie also wasn't immediately aware that when she returned home, she would for the first time in what seems to be many years meet up with her cousin, K.C. Howard had to be pleased to see both his daughter and niece at the same time, as was Marion. After the meeting, I wonder if Joanie and K.C. happened to be fans of Looney Tunes after going through that cute cheer of theirs. Chachi introduces himself to K.C., and mentions something about Barnacle Bill the Sailor. While Joanie and Chachi leave for the local TV station to perform on "Hootenanny", Fonzie is still having a little bit of trouble adjusting to the changing times, thinking rock-n-roll music was in trouble, but after awile, Ashley brings him to his senses about his views on music and the changing times and they leave for the show, afterwards. K.C. and Jenny had already left for the TV station to see Joanie and Chachi perform folk music, instead of rock-n-roll like they wanted to. In the end, they got their performance off on the TV show, and the audience applauded. Later, Joanie and Chachi would perform on stage at Arnold's Diner, but so would K.C., Jenny and their friend, Julie, and they would perform in front of Fonzie and his mechanic on prison work release, Jim, whom K.C. would fall for. I wonder if Joanie was aware that her cousin, K.C.(with Jenny and Julie) has done exactly the same thing she(along with Chachi) and brother, Richie(with Potsie and Ralph), before her, have done-entertaining the patrons on stage at Arnold's Diner? She probably does! Now, chime in with your thoughts about "Who Gives a Hootenanny".

not to put a damper on this thread but i just never really liked this ep it was one that showed that by season 10 the writers were really running out of ideas even though im very awre of the folk reveluiton of the 60s the ep as a whole just wasant very good

not one of my favorite eps either, but I was never a really big fan of Joanie & Chachi's "band"
