A children's tune. I surely do not believe in angels, and I strongly doubt there is „something good in everything I see“. And the kids choir in the recording is definitely over the top.
But nonetheless I just love this song.
Apart from the flowing beautiful melody, this is a good exercise on melody lines in thirds. During melody breaks and long notes, you can arpeggiate the chords freely (what is tabbed is just a suggestion). In the repetition, that one bar in the verse marked with a red x is modified. The high note is sustained two beats longer. Replace that bar with the phrase noted on the second page. The sequence is easy, just repeat everything twice (including the intro).
