I was also in the fifth grade when this show was on CBS and watched it every Friday night. Then I probably liked the angel gimmick but in the 1980s, when Nick at Nite reran the show, I found that the only funny parts are when Tom and Dick go into their basic routine--bickering with one another--which I had forgotten occurred at least once a show. However, the show does not appear as dated as "The Smothers Brothers Comedy Hour," no doubt because the sitcom did not rely on political humor.
The way I remember the theme lyrics:
Tonight you'll meet two brothers who Just happen to be us. But Tom is slightly different, a problem we will now discuss. My brother Tom was lost at sea Without his water wings. And now he is an angel And he tries to do amazing things. That's right. Brother Dick, it's no trick if you see Lots of different faces that look a lot like me. An angel on a visit to his brother here below Can cause a lot of trouble. There's miracles to start but they always come apart On The Smothers Brothers Show.
