I liked the "Celebrities Talk About Adam Lambert" videos. Thanks for posting them.
One quote I really liked was from 2009, when EW interviewed Jim Parsons (who played Sheldon on The Big Bang Theory). They asked what must-see TV show he was watching that year, and he replied American Idol, adding, "There's a fellow on there, Adam Lambert. I like him because he always knows what he's bringing to the party." (Or words to that effect.). I thought that was a pretty good description.
