LOS ANGELES (AP) — Chicago keyboardist Robert Lamm acknowledges he jumped the gun when he said Peter Cetera would sing at their Rock and Roll Hall of Fame induction in April. Lamm tells Billboard magazine he misinterpreted his email exchanges with Cetera and he spoke out of turn when he told Radio.com that Cetera would sing but not necessarily play bass at their induction. Lamm has apologized to Cetera and the music press. Cetera himself has not said whether he’ll even attend the induction, nor has drummer Danny Seraphine, who quit Chicago in 1994.
