Knapweed? (No)

I photographed this flower in my neighbor's yard.  It might be some sort of Knapweed - but what do I know?  I'm not a trained botanist.  Anybody out there know what it is?

I'm also glad to see the bee in the photo.  I like bees. The yellow flowers behind it are Whorled Yellow Loosestrife .

EDIT - I have been told, by my friend AJF, that it is (most likely) Monarda didyma - otherwise known as Crimson Beebalm.  Hooray!

I photographed the same flowers last summer.  You can see that photo here.
