This is a lightweight episode of Happy Days (I guess like just about all of them) where a tired Fonz just rolled his broken motorcycle twelve miles home to dance in a marathon with Joanie.
For Joanie/Erin Moran fans it's a great episode as her character pretty much dominates here, and she even has a sweet moment with brother Richie.
The as always unnamed band, consisting of Richie, Potsie, Ralph and the mystery girl drummer who never speaks again (played by an extra who is in tons of Happy Days episodes) are slated to provide the music for the marathon, and at one point many hours in, Potsie says he can't sing anymore, so Ralph sings a tune.
Donny Most does a great job, and in my humble opinion, has a better voice than Anson Williams, who is supposed to be the "singer" on the show. Donny's voice just has a better resonance, and is more pleasant to listen to. Anson's voice sounds way too smooth and frankly, dull (remember "Dull Potsie"), like a one-trick pony.
The funny thing is, Donny Most is the one out of the two who actually recorded a full album, while Anson just recorded singles. Donny's album came out around the time of this episode so it seems they were trying to promote him a bit. I wonder if any commercial time was bought during Happy Days airings for advertising the album.
The album didn't chart, and both Donny's and Anson's singles lingered at the bottom of the charts (others they did didn't make the chart at all). It's a bit surprising considering how gigantic the show was.
Donny's one pop album from 1976 is on Spotify, and the production is poor unfortunately, like many quickie cash-in attempts then when TV shows churned out record albums featuring stars from the shows. He was a Barry Manilow fan though, and there is a nice version of Manilow's "One of These Days" on it.
Of course, nowadays Donny records jazzy/swing music, and he sounds darn good.
So that's really the highlight of this episode, seeing Ralph Malph sing. Of course, Joanie is cute as is her main competition, Charlene Tilton.
