Chuck Behler was hired as a drummer in Dave Mustaine's Megadeth early 1987, replacing previous drummer Gar Samuelson. The latter was fired after the last show of a tour in Hawaii in November 1986.
With Behler on drums the band released "So Far, So Good... So What!" in 1988. However, in July 1989 Nick Menza was hired, replacing Chuck Behler behind the drum kit.
