What everyone remembers are the Beatles and Elvis. What they forget is what people were forced to sit through.
This was before Tivo, videotape, or streaming. The only way to see the classic performances was to sit through 40 minutes of tedious bad circus performers, over the hill vaudeville comics with jokes that were old before you were born, and corny schmaltzy over the top "singers."
If you had to work, or even ran to the bathroom, you missed it. This also means even the greatest performances on Sullivan became badly overrated. The Beatles were amazing songwriters, but as live performers were just slightly better than average. Elvis was amazing live, that is, before his Vegas days. But on Sullivan they notoriously censored him from the waist down.
So watch, but be prepared to fast forward a lot. A lot. You'll finish a 40 minute episode in seven minutes.
