Former Dancing With the Stars host Tom Bergeron is looking back on how he first got involved with the show ahead of its 20th anniversary extravaganza. "Well, it really took some convincing," Bergeron, 70, admitted during the Wednesday, November 5, episode of Good Morning America. "A celebrity ballroom show, I thought, 'Really?'" His hesitation didn't last long, however. "Then I agreed to just look at Strictly Come Dancing, they were gonna send me a DVD of the British show - the mothership. And I said, 'Look, I won't answer yes or no until I see that,'" he recalled.
