Steve Perry
Steve Perry Quits Journey:
Steve Perry led Journey from 1978 until he and the band went their "separate ways" in 1987. Despite early solo success with 'Oh Sherrie,' by 1995 he was ready to resume knocking out power ballads with his former bandmates. Perry retuned to the sidelines after a 1998 hip injury -- and has since been replaced by pint-sized Filipino karaoke star Arnel Pineda -- but if he asked nicely, the band would surely welcome him back with "open arms."
