After speculation that Peter Cetera would reunite with Chicago for the band's April induction into the Rock and Roll Hall of Fame, the rocker has opened up on his decision to nix the reunion.

"Every idea or suggestion I offered about how it could work musically was either rejected or changed by the show's producers," wrote Cetera on his web page.

"Together with the fact that while I sent those same emails to the group, the only reply I ever received back from them was a very snarky 'Take a chill pill, dude!' Whoa! Really?"

"At this point in my life," he continued, "I don't care to reintroduce the same negativity, misplaced egos and petty jealousies I left behind years ago."

Cetera left the band in 1984, following the release of Chicago 17.
