Let's dance has some lovely orchestration and arrangement, and thougtful lyrics, but the heart of this songs is the cut through that happens with the riff that comes in over the I to IV chord change (D to G).
I'd recommend playing this like Chris does, with right hand fingers rather than with a pick. As always the trick is to start slow and pick up speed. Some of Chris' liveĀ versions are at a fair 'aul pace. (Even faster that 160 bpm)
There is quite a bit of palm muting as you plck the 2nd and 3rd string. This is essential to get the crisp percussive effect that emulates the 'stabbing' of a horn section. Basically think of your self as playing 2 notes notes as though you are two trumpets harmonising.
You can add the 'D' note on the open 4th string at the beginning of each bar also. There are a lot of the strikes on the off beat so there is a continual sense of syncopation. (We're dancing, right?)
