Because some people presumably can pat their head and rub their stomach at the same time, this is a video of musician Pat Hinds performing Dire Straights’ ‘Sultans of Swing’ on a double harp guitar, with one hand performing the guitar medley, and the other the bass line on the harp. At least to me, that’s extremely impressive, but the last time I tried clapping I gave the guy next to me at the concert a black eye.
