What key(s) harmonica does Bruce Springsteen play?

I reckon that the reason why nobody's replied to Your question is that it's pretty much impossible to figure out... I've been looking at Springsteen videos for an hour now to figure it out for You, but it's virtually impossible...
Is he blowing or drwaing at exactly which note, or it's a Live performance where You simply can't make it out because of shouting fans...
Post a link to a youtube video where You think it's clear enough and I'll have a go again for You?
Sorry for now...

I haven't answered because I'm not all that familiar with his stuff. What songs does he play harp in? What keys are those songs in? What positions does he play?

The only answer I could think of sounds kind of snide but it isn't meant to be.
Answer: Whatever the song calls for.

Here's two videos where you can hear the harmonica without any crowd interference. 1st one is a studio recording, the other recorded "live" without an audience.
