Would have to be an iconic band - Queen is an excellent choice.
Led Zeppelin would be a real winner - and if the rumors are true about a reform in 2014, then this is the logical choice.
I think the only other Band that Stern could look at would be Bon Jovi or Iron Maiden.
Led Zeppelin rumours have been flying around since 1981. They will never reform according to their press statement in 1980 and besides, Robert Plant's voice probably peaked in 1975. He is happy doing what he likes and is comfortable with.
A 4 December 1980 press statement stated that, "We wish it to be known that the loss of our dear friend, and the deep sense of undivided harmony felt by ourselves and our manager, have led us to decide that we could not continue as we were", and was simply signed "Led Zeppelin".
A Zeppelin pinball? You would need a mighty good ball to complete Kashmir or Stairway. Dazed and Confused? I have a bootleg version that goes for 35 minutes!
Zeppelin are very protective of their brand and material. The rights to create a pinball would probably add at least 2K per machine.
They all say they won't reform, but for the right price, they will - Just ask KISS, The Police, Van Halen and Sex Pistols. BIG money has been thrown at ABBA and Led Zeppelin. A recent interview on 60 Minutes with Robert Plant hinted on a reunion in 2014. Robert Plant is willing and able. The stumbling block has been Jimmy Page and John Paul Jones. Recently it has not been a "money issue", rather the desire. Would the line up with Jason Bonham live up to the legacy left by the band in the 70's ? So much amazing material has surfaced on Youtube etc - If Led Zep allowed their name on a pinball, it would have to be the very highest standard. I think they will reform, even for a handful of shows.
