It is reminiscent of the reggae style from the first chords, though the melody a little fast for canonicity performance. Sounds of maracas, sunny voice of performer, cheerful and relaxed chorus with the promise that everything will be fine, and there is no reason to worry are a universal recipe to move easily into the light world without any problems. Chirping birds in the background became the best complement, after which the song, apparently, was named.
