But isn't this more of a technicality in the timing of licensing? Because the new version isn't yet available? I'm not sure the old version will be an alternative one allowed once the revisal is available. I've never heard any of the collaborators express feelings that both will be performed in future. If anything, everyone has been confident that the new edition is definitive. This may be a transition period, until the current materials are prepared, available and can be contracted. Licensing various editions of musicals is complicated, and the original creators are often protective of properties one they undergo significant changes. I saw both versions of SIDE SHOW more than once and I must underscore: the changes are rather radical, not just tweaks. The first act has been entirely rethought. This isn't just like, say, using a different version of "Last Midnight" in INTO THE WOODS.
