Chicago has been eligible for the Rock and Roll Hall of Fame ever since their debut album, The Chicago Transit Authority, celebrated its 25th birthday in 1994. But they never even got onto the ballot until this year, a situation that enraged their passionate fan base to no end. To Chicago co-founder/keyboardist Robert Lamm, however, it was never that big of a deal. "If you're nominated for a Grammy and you don't get it, you don't have a heart attack," he says by phone just a few hours after learning he'd gotten in. "You just move on and keep working. That's really what my attitude always was."
