Ellefson was fired from MEGADETH more than two years ago after sexually tinged messages and explicit video footage involving the bassist were posted on Twitter.

David was in MEGADETH from the band's inception in 1983 to 2002, and again from 2010 until his latest exit.

In 2004, Ellefson filed an $18.5-million lawsuit against Dave Mustaine, alleging the MEGADETH leader shortchanged him on profits and backed out of a deal to turn Megadeth Inc. over to him when the band broke up in 2002. The lawsuit was eventually dismissed and Ellefson rejoined MEGADETH in 2010.

Young's entire career with MEGADETH was spent recording and touring in support of the band's 1988 platinum-selling album "So Far, So Good...So What!"

Jeff made headlines in December 2009 for accusing Mustaine of, among other things, "dissing, exaggerating and just plain lying on some level about nearly every talented musician that has passed through his dysfunctional little ensemble." He also disputed Mustaine's claim in an interview that Young's drug problem led to MEGADETH's 1988 Australian tour being called off and the group being "banned" from performing in the country.

Poland was a member of MEGADETH from 1984 to 1987, during which time he performed on the band's classic albums "Killing Is My Business... And Business Is Good!" and "Peace Sells... But Who's Buying?" He is also a featured soloist on the group's 2004 album, "The System Has Failed".

Back in 2004, Poland and/or his management and attorney filed a lawsuit against Mustaine regarding the use of the three "Rust In Peace" demos on the album's reissue without Chris's permission. Chris eventually settled for $9,500 and thereby ended a professional relationship with Dave and MEGADETH.

For the past couple of decades, Poland's main musical focus has been the fusion band OHM:, which has released several full-length studio albums to date.

Behler played with MEGADETH from 1987 to 1989 and appeared on "So Far, So Good… So What!"
