Springsteen concert leaves me speechless

The Bruce Springsteen concert was smashing. Left me speechless.

Really. I literally can't speak. Or is it hear? Definitely one of the two. Whichever is the one where you find yourself in a bar after the concert and you say to a pretty girl, "Can I strap my hands across your engines?" and, in reply, she furrows her brow, starts moving her lips at a rapid rate, but nothing comes out except a kind of burbling like a loudspeaker under water and some crackling noises? Then she slaps you?

So maybe it's hearing. It's definitely one of the two.
