One of my favorite eps is the one with Chad and Jeremy as The Redcoats, during the initial onslaught of Beatlemania. They were very 'fab' like, and I still remember one of the songs they did- 'My How the Time Goes By'. Obviously a little lightweight for the radio, but for a 'tv pop song' it wasnt bad! I recall they were also on a Patty Duke show around the same time.

I liked their TV songs better than their real ones...

I don't like this episode.

I wouldn't mind seeing that episode again. Wonder which season it was on?

Season 4. If you have the complete series set, it's Season 4 Disc 3.
I like the girl who was crying, and Rob took the last pillow from Laura and gave it to the girl and she ran out. It was cute.
Also, was the one girl who came to their door the same on who played Ursela in the movie Bye Bye Birdie! with Dick Van Dyke? It sure looks like her.

^ I guess I'll have to break down & buy season 4. I only have the first two seasons on dvd, so far.
