Best realization at a concert, ever.

Last night, during the U2 show at Reliant -- which, by the way, was amazing; it really takes something to pull off a credible rock and roll show at that scale, about which much later -- Mrs Heathen pulled my arm to yell in my ear:

"When's the last time we heard this?"

The song was "Beautiful Day." The answer: January 18, 2009. At the Lincoln Memorial. With about a million of our closest friends, in the cold and wet joy that was the pre-Inaugural concert.
