For the faithful followers of the contestants on American Idol, this news can be very interesting. During the morning of Friday August 7 presented at Good Morning America, the champion of the seventh season of "American Idol" David Cook. He was accompanied by two of his closest friends: he is the champion of the eighth season program, Kris Allen, and runner-up Adam Lambert.

David Cook, backed by his band of four, played the opening theme "Little Lies" by Fleetwood Mac's, but then, unexpectedly, he announced: "Ladies and gentlemen, I need to do a lot of noise to Adam and Kris Lambert Allen ". At that time the two appeared from behind a microphone in hand

and facing the great joy of the whole crowd began to take turns singing different verses. Finally the three were joined in the chorus.

At the end of the track all three smiled and bowed to the people who cheered wildly at Central Park. In addition, each performed a song separately. David Cook did his hit "Come Back to Me", Adam Lambert sang "Starlight and Kris Allen showed his talent with" Heartless ".

Cook had previously performed a solo version of the song "Little Lies" earlier this year on "Jimmy Kimmel Live." In this case it was fairly new to incorporate these three very different but complementary voices.
