We're going to use the following chords:
A major 7
F# minor and F# minor 7
D major 7, played like this.
[[The sequence of those last 3 chords is very common.]]
[[And finally A minor 7.]]
[[Now let's play the verse, slowly.]]
The song starts with 2 whole notes (semibreves): an E then a G. In the original song, they're played on the piano, but you can play them on the guitar instead.
And here's the refrain, played slowly.
Now let's play both the verse and chorus/[refrain] at the original tempo.
[[B minor 7 and Asus2]]
