Reply #50: According to James Hetfield of Metallica...

[Amerigo Vespucci]

...who was asked "What are you going to do with Dave Mustaine," his reply was that induction is based on the recording members of the band, and since Mustaine never recorded with Metallica, he wasn't eligible.

So it all depends on how well the band is getting along. My understanding regarding the fact that the last reunion didn't include Gabriel or Hackett was that their schedules had more to do with it than their desire to participate.

That means all of the band members below are eligible for induction:

From Genesis to Revelation (March 1969): Peter Gabriel (vocals), Anthony Phillips (guitar), Tony Banks (keyboards), Mike Rutherford (bass & guitar) and John Silver (drums).

Trespass: John Mayhew replaces John Silver (drums).

Nursery Cryme, Foxtrot, Genesis Live, Selling England By The Pound, The Lamb Lies Down On Broadway: Phil Collins replaces Mayhew, Steve Hackett replaces Phillips

Post-Hackett & Gabriel: Daryl Stuermer (who replaced Hackett onstage, but not on the studio albums, which were played by Rutherford) is eligible because he's appeared on live albums. The same for Chester Thompson (drums).

ON EDIT:

Forgot Ray Major, from the regrettable "Calling All Stations"...

...also on that album, the drum chair was filled by Nir Zidkyahu and Nick D'Virgilio (Spock's Beard).
