Yo-yo'ing up and down the East Coast to see Bruce Springsteen in concert was how I spent my 20s (along with working in unfulfilling jobs and drinking). So I'd planned on previewing his concert Saturday night with the E Street Band at the KFC Yum! Center with a long-winded self-indulgent preview, trying to explain what about Springsteen live has compelled me to see him more than 50 times.
