[ Предположительная тональность: Eb ] I haven't found these chords anywhere on Internet. I needed the chords for my English class with Spanish primary school students. They love this song, so I had to transcribe it so they can sing it along with the original English version and me playing over it with my electric guitar. It looks like a lot of fun for them. So here it is for anyone who might need to use it too. First verse, C-7 with G on the bass could be played as Eb, but G on bass, on a Eb triad does not sound good at all. The same stands for the Bb-7 chord and the F on the bass . It could be played as Db triad with same result; it does not sound fine. The last part of the theme (from Ab and so on) I play it with no roots. If you play it with a bass player, let him do it. So basically I play the fifth chord tone on fifth string, tonic on fourth and the third chord tone on third string. Then I finish with the Ab final chord playing root on sixth string and vibrating the whole chord with the tremolo bar (whammy bar) until stop. I sounds pretty good this way. Of course, you will need some distortion (although not too much). The song is on Ab major but it could be that, because the arrangement has a brass section (instruments on Bb and Eb), the original guitar player might be tuning the guitar a half tone lower (Eb tuning on sixth string) and then playing the song on A major.

Note (April 20th 2015): Song original name is "Today Is Gonna Be A Great Day". It is longer than the version I transcribed from the TV series, which are the chords following this note. Ab C-7/G There's 104 days of summer vacation Bb-7/F Ab And school comes along just to end it Ab C-7/G So the annual problem for our generation Bb Eb Is finding a good way to spend it Like maybe...
