Gacy

Madonna Wayne Gacy aka Pogo had never picked up a keyboard prior to his inauguration into Marilyn Manson in 1989. It's been said that it took him less time to master the keyboard than the time he spent saving money to buy one.

Pogo's brilliance is justified by Manson's convincing him to decline a job offer at Nasa to join the band. Gacy has parted his ways with Manson in the middle of 2007.
